      I feel like all "non-inner-circle people" here are taken for a laugh. OpenAI and these security companies sat on this for 2 months, decided for themselves who gets access to an early fix, and then leave the rest out to dry while they failed to properly contain it.

      The official interim fix for php8.5 [1] could have been published 24h ago, or even 2 weeks ago, without revealing any security details. Specifically once the POC came online. Would have been significantly more useful than these polished blogs.

      Perhaps I'm missing something here, but the costs (dev/sre time, missed sales, potential data leaks and hacks) of the way that this was handled is significant.

        >OpenAI and these security companies sat on this for 2 months

        these security companies reported it 2 months ago. it took a month for the php security team to acknowledge it and another month for the php team to develop & release the patch.

        if you're going to be upset at anyone it should not be the reporters.

        >The official interim fix for php8.5 [1] could have been published 24h ago, or even 2 weeks ago, without revealing any security details.

        publishing the fix = publishing the security details.

          This really sounds to me like "they filled out some webform" or "sent an email to security@php that read like any of the ten billion we found vulnerability in your code please send money emails they get.

          If I had details on a RCE like this I'd report it but if I got no response for a WEEK I'd be trying other venues.

          • dannyw 54 minutes ago
            I imagine more details will come out over the coming days, but it’s not uncommon for severity to be under-estimated in the beginning; and then “oh shit” as you dig deeper.

            We don’t know when it went from a “memory safety issue” to “php2shell/RCE”.

            Calif’s report is a little light on timelines, but reading between the lines, it seems they took a while to turn this into an actually exploitable vulnerability.

            Finally, at least pre-LLM (and maybe a bit outdated now), responsible security disclosure norms is that you usually do wait for vendor (up to 90d) if there’s no signs of active exploitation. Even if it’s a RCE. Actually, especially if it’s a RCE.

            The last thing you wanna do is go pinging random non-security PHP contributors or maintainers and have it leak with zero patch. That is truly the worst outcome.

            Yes, this is bad, but also, it’s apparently been bad for decades; and it could’ve been much worse.

            • Maxious 47 minutes ago
              According to this post, one of the researchers was a former PHP security lead who already knew about the bug since 2004. So I'd assume they would be taken as credible by the current team https://calif.io/php2shell/
              • Twirrim 13 minutes ago
                Assuming that it could have been spotted in their inbox, amongst a probable flooded of LLM slop like a number of security mailing lists for open source projects that I know of. We've all seen the impact on open source github issues, hackerone etc. The same is happening to standard email disclosure paths.

            i highly doubt it. these are pretty big names in the security sector who have plenty of experience reporting high severity vulns.

          Why does the PHP security team need to acknowledge it and develop the fix? It's open source software.
          • lokar 1 hour ago
            If you want an orderly fast global rollout you need to have the maintenance team and distributors working together.

            So anybody can just push out a new release of PHP?
            • swiftcoder 46 minutes ago
              Sort of by definition of open-source, yes. It's just that nobody downstream is likely to accept Joe Public's random fork of PHP.
          • justinhj 56 minutes ago
            What would you have a security team for then?
          • wat10000 51 minutes ago
            What's the other choice? OpenAI et al could have developed a patch (for all we know they did) but you need the PHP team's participation to get it out. The alternative would be to fork the project and put up a forked release with the fix, which would have been incredibly disruptive.
      • dspillett 54 minutes ago
        One concern with the current environment is that as soon as a release comes out for such an important open source project, people will immediately point bots at the release to look for changes that might be related to existing security issues. This means that putting out a quick out-of-band release is guaranteed to result in people racing to exploit the problem before many even know there is an update out.

        Whether keeping the update quiet and including it in the next normal release, where there are more trees obscuring the wood that is the security concern, and announcing the bug a short time later once anyone using distro updates or otherwise keeping on top of things have updated, would be safer overall than what has happened today is up for debate. I can think of arguments in both directions.

        --------

        [1] which does have a slight whiff of AI marketing about it - would a human-found issue, without the option of a big AI company to claim some credit, have been handled differently?

        • chilmers 37 minutes ago
          This is not a "concern", this is literally what happens. Even prior to AI vulnerability scanning, release notes and diffs for any normal release or security patch of popular software were analysed and used to develop exploits, which could then be applied against non-upgraded instances. Nowadays, AI is doing this en masse and automatically producing exploits. And, as has been demonstrated, nowadays even the rumour of a major security bug is enough for people to find it, as people will immediately burn huge volumes of tokens looking for it.

          Nor can you just keep it quiet and smuggle it out in a regular release as you suggest. For one thing, changes in important software are be linked to commits and have pull requests, reviews, etc. Changes without these will immediately raise suspicion, as either a malicious change snuck into a release, or as a "quiet" fix to a major vulnerability, completely undermining the purpose of keeping it quiet in the first place. Moreover, major vulnerability fixes cannot be "quiet", because the whole point is to get as many people as possible to upgrade as quickly as possible. If PHP (or whoever) push out a release containing a major security fix, but don't make this clear, then many people will be in no rush to upgrade, and will get pwned.

      • dannyw 1 hour ago
        Maybe the NSA ‘requested’ some time to use the exploit on some high value targets.

        Sure, it’s PHP, but plenty of companies or organisations might have some PHP running somewhere; and once you’re in, lateral movement becomes a lot easier.

        • DaSHacka 11 minutes ago
          The NSA does not need to "request" time to use an n-day vuln. They have more 0-days than you can imagine.

          They literally employ full-time Vulnerability Researchers doing nothing but 0-day discovery and PoC creation 24/7 to add to their horde. Plus contracting with the MIC for their full-time VRs for the occasional project.

        Php core security team decided who gets to know. The patch was huge it took that long.

      > Over the past two months, we led a coalition of maintainers, researchers, and security providers to address critical vulnerabilities in PHP, an open-source programming language used to run websites and web applications.

      And they botched this as someone talked. To me this looks like they used this for a PR stunt and aimed for an RCE.

      • giancarlostoro 56 minutes ago
        If I understood the timeline correctly, there was an announcement made somewhere that an RCE would be announce w/ a patch, and the internet just scanned the entire codebase, they really fumbled this for the sake of having a PR post for OpenAI.

        On the other hand, I don't mind AI companies doing this sort of thing, I'm sure a lot of our internet infrastructure could benefit from these sorts of fixes and changes.

        They haven't even been able to release the patch on time. Ubuntu still hasn't it
        • dspillett 1 hour ago
          Debian has, though only for current stable (updates for oldstable and oldoldstable apparently about to drop) which might imply they had no advanced access to the update so could not pre-test and release immediately upon the coordinated announcement.

            Still no update for ubuntu 20.04 which has support via ESM, even though the patch is available for php 7.4. There are a lot of people using older servers which still have ESM support.
          • kijin 44 minutes ago
            Anyone using a non-default version from the semi-official PPA by Ondrej Sury is still waiting for an update.

            The launchpad server is throwing 503 errors all over the place, so that's probably the reason for the delay. Sury's own repo has the fixes all right.

        Took them almost 7 years even. According to the Calif write-up it was already reported in 2019 (https://bugs.php.net/bug.php?id=78876) and 2024 (https://ostif.org/php-audit-complete/).

          • pixl97 1 hour ago
            This isn't a terribly uncommon method of 'discovery'. In maths and sciences there have been tons of papers that have highlighted something new but were never really connected to anything else and then largely forgotten. Later they are picked up by someone else and connected to a much bigger whole.

      Why is WordPress out of that list? Isn't it the single major PHP installation in the whole Internet across hosted and self-hosted instances?
      • trollbridge 1 hour ago
        Well, WP is just a program written in PHP.
        • dspillett 1 hour ago
          One of the most common PHP based applications out there, therefore a good comms channel (via their forums and any mailing lists, both public and for people who have managed instances with them or are otherwise paying for support contracts) to make sure people are aware of the need to update. That would make the company one worth keeping in the loop, if only in one direction, I would have thought?
          • trollbridge 1 hour ago
            Well, it would help if WP were actually controlled by one entity, but currently it's dominated by factions and infighting.

    • OJFord 1 hour ago
      Same on the older few. I'm not sure I understand it though, seems strange you can have a tag for a commit that's only present in a fork?

      Is it perhaps a bit misleading, and only means that there's no branch containing that commit?

      • CodesInChaos 22 minutes ago
        There is little difference between a tag and a branch in git. There is just the convention that tags reference the same commit forever, while branches move.

        And on github forks are part of the same physical repository. You could imagine that each logical repository is just a namespace for branches and tags, backed by the same physical repository.

      • cyberclimb 1 hour ago
        It can mean either, it's a consequence of how github optimized their backend storage so a 100 forks of a repo initially take up the same space as 0 forks

  • deanc 28 minutes ago
    I think there's a lot to learn from the last twenty four hour's events. An absolute nuclear bomb of an exploit affecting every version of PHP back to 2012 (which nobody should be using of course, but I've worked in plenty of environments that are not up to date).

    The thing that's annoyed me the most is the speculation and misinformation, filling in the gaps. Folks looked into the php-src and figured out one of the vulnerabilities, starting saying you should disable certain php settings and then core PHP developers on obscure mailing lists hinting this isn't enough.

    Given how inexpensive it is for agents to scan popular OSS projects, disclosure needs to be more discrete and you cannot publish fixes to OSS before disclosure. People will be and are watching for this kind of thing already.

      Many vendors do it, but on a set schedule "patch Tuesday" and some will release vague "mitigation steps" but honestly those usually come with the patch.

        Yeah… it was patched in the source 3 days ago. Check the linked GHSA.

    This reminds me of the old days when PHP was such a vulnerable language.

    By simply searching for websites that used local includes to load other pages, you could get RCE.

    At this point, running webapps in JS workers/sandboxes sounds like a good idea. Vendors take care of patching.

    So they've added malloc fail checks and tests for malloc fail throughout.

    Is this even reachable on Linux due to overcommit? Maybe by attempting a single extremely large allocation?

      PHP is tracking its own memory usage internally with limits configurable via php.ini.

    Time to restart Apache again!

    "I'm not a real programmer. I throw together things until it works then I move on. The real programmers will say 'Yeah it works but you're leaking memory everywhere. Perhaps we should fix that.' I’ll just restart Apache every 10 requests." -Rasmus Lerdorf

      Amusingly enough restarting php after each request seems to block the issue

    What I did on our WordPress boxes while waiting for distro packages (CVE-2026-109618 / CVE-2026-109619)

    1. session.upload_progress.enabled = Off, in php.ini and as php_admin_flag in every FPM pool, so per-directory config can't turn it back on. It's one of the two confirmed consumers in GHSA-6wmf, and the validated FPM path depends on it. Almost nobody uses it, and the advisory suggests leaving it off even after patching.

    2. Refuse multipart request bodies at the web server, before PHP parses them. All of the GHSA-w8hw out-of-memory strategies go through multipart parsing. On Apache it's a rewrite rule matching a Content-Type of multipart/form-data that returns 403. On Caddy it's a header matcher that responds 403. The cost: every browser upload breaks (media library, plugin zips, importers). Check your public forms first.

    3. Check your SAPI. Both bugs have confirmed RCE against mod_php. FPM is narrower: the validated path needs upload_progress, and the early INI consumer only applies if your front end sends PHP_VALUE/PHP_ADMIN_VALUE. To check, grep your Apache, nginx and Caddy configs for it, and run apache2ctl -M | grep php.

    4. pm.max_requests = 1 in the pools. A worker serves one request and exits, which breaks the stale-state chain: the "producer" and "consumer" requests must land on the same worker. It costs a fork per request.

    5. Lower max_input_nesting_level and post_max_size, per the advisory.

    6. Housekeeping that should already be done: no .php served from uploads directories, and remove any stray phpinfo.php. Scanners request it constantly, and it tells an attacker your exact build.

          I’d rather just some sort of tag. Because sometimes it can be useful. This is a case where the community here can scrutinize the output and actually pull out useful data or steps or even starting points when information is coming in so fast for a developing story/issue
          • bombcar 1 hour ago
            The (pretty obviously Claude'd) responses with actual steps you could take to mitigate were 1000% more useful to me than the "SHUT EVERYTHING DOWN WE'RE GONNA DIE" and the "stop posting AI slop" posts were, that's for sure.
            • dwedge 51 minutes ago
              It was your response. Of course you prefer your response.

              The fact is you had no idea how useful or dangerous your advice was. PHP maintainers said to shut it down, how many people followed your advice instead? Did it work or just leave them vulnerable? Do you know?

              Because you're heavily implying that the people who knew about the details of the vulnerability were panicking and thank god we had you with an LLM

      • bombcar 1 hour ago
        It's just Claude output of what I've done; the other URL has the basics.
      • DonHopkins 1 hour ago
        Why don't you do something useful and rewrite it so it's not claude output any more, but says the same thing in a way that you're satisfied with?

        Then your own comment would not be such low effort and useless human slop.

        Do you agree or disagree with the comment's claims? Did YOU verify anything? Let's all hear you fact check and proofread and reword what it said so it matches your standards, instead of just listening to you bitch and complain without offering any useful information.

        Or do you not actually know anything about PHP administration, programming, and security, so you're only capable of information-free drive-by anti-ai posts, without any other useful content or corrections?

        Ball's in your court.

      People have been saying this for the past 16 years, but the reality is once a system is in production over time it becomes increasingly risky to replace it. Because over the life of a piece of software you make tons of small fixes, resolve bugs, adding customer-specific functionality, etc. that you'd completely overlook when planning our requirements for a rewrite. Which is a big problem when other systems are dependent on the software operating a specific way i.e. APIs, web services, and so forth. Not to mention the economics of a rewrite also has to make sense. Nobody is going to spend 2-3 years recreating what they already had and get no additional functionality out of it. Certain software basically has to get so bad that literally anything replacing it is better than what came before for replacing it to be the right approach.

        People shouldn't be using PHP. I was shocked some security focused websites are even using it. I just hope there's nothing of value on their servers and that it's not connected to their internal network in any way. In my experience this is almost always the case because it makes maintenance and development easier but effectively exposes your entire organization to the internet.

        That 70% of the internet still uses it is shocking to me. The organizations that do deserve to get burned badly. Let this incident be a warning to all of them!

    For anyone who can't patch their PHP for some reason, here is a proxy that eliminates the threat for you -- it's open source, you can add it to your servers:

    https://news.ycombinator.com/item?id=50181752

    https://github.com/Qbix/proxy -- open source MIT licensed, I made github actions compile it as a Cosmopolitan binary so it can work across many operating systems (thanks Justine)

    I wrote it so I could deploy it myself on our old nginx + php-fpm setups, thought I would share. It should work with all top servers (nginx, apache, caddy etc)

          It's free, MIT open source. It was the best I could do. Run it under a Linux user with no permissions to access anything. All it's supposed to do is proxy requests. Don't give it access to any files.
      • EGreg 1 hour ago
        You know, normally I'd be okay with these comments, but in this case you're actively hurting a lot of people by this bullshit. Many people need something other than patching PHP.

        It's free and MIT licensed, open source and it is currently the only alternative to patching your PHP. The "profit" is for people who don't get PWNED today!!!

        Many people can't patch your PHP. If you can't be bothered to even look at the repo, you may want to sit this one out.
