PHP web runtimes (CVE-2026-109618 and CVE-2026-109619)

We didn't get much information throughout the day, besides these comments by an AWS employee/Amazon Linux maintainer on this thread: https://github.com/amazonlinux/amazon-linux-2023/issues/1148... He referenced an nginx Important CVE taking 20 days to be patched - after it was noted that these PHP CVEs were also labelled by AWS as Important (not Critical). This employee took issue to another user's comment describing 20 days as "nearly a month". Amazon Linux users/AWS customers barely got any tangible information from the CVE publication at 14:00UTC until this bulletin was posted at 21:30UTC. Very disappointing.

  Where, exactly, does Amazon classify the PHP RCE as Important? I'm not sure anything says what your editorialised title, and comment link says. They were calling out that an NGINX CVE that was Important took 20 days. They're saying nothing about what classification Amazon has set on PHP,. > So, from the CVE publication to an available fixed package it took 20 days, not a month. They specifically call out that it's not the same as the Nginx case: > In contrast to the PHP's case, that CVE wasn't Critical, but only Important, that doesn't have the same urgency.

    https://explore.alas.aws.amazon.com/CVE-2026-109618.html https://explore.alas.aws.amazon.com/CVE-2026-109619.html Both are labelled Important, not Critical.

      Heh, what is critical in their eyes? Catching the servers physically on fire?

  It seems to me that this comment is just regarding an earlier vulnerability and doesn't comment on PHP2Shell?

Amazon has a bad track record for delivering critical updates quickly. During the Copy Fail - CVE-2026-31431 event they were behind every major Linux distro in updating Bottlerocket OS

• captn3m0 · 1 hour ago

  Bottlerocket's changelog through the storm of Linux CVEs these last year has been bad as well: https://github.com/bottlerocket-os/bottlerocket/blob/develop... Roughly one release every 15-20 days.

Patch releases are currently scheduled for tomorrow (October 22): https://aws.amazon.com/security/security-bulletins/2026-143-...

Update: After posting this Amazon security released a bulletin to say we should see the updates _some time tomorrow_. https://aws.amazon.com/security/security-bulletins/2026-143-... Scant messaging throughout the day. I don't understand why AWS, seemingly, didn't have prior knowledge of this/have it ready very soon after the CVE announcement.

  > Scant messaging throughout the day. I don't understand why AWS, seemingly, didn't have prior knowledge of this/have it ready very soon after the CVE announcement. Posts elsewhere have suggested that the embargo was broken early. Even the PHP release team itself didn't have sufficient time to update their public Docker images before it was published.

  • hayd · 45 minutes ago

    My understanding is the embargo was scheduled to end 14:00 UTC today, broken 07:41 UTC by Chainguard... It's now 22:00 UTC and AWS are talking about (some time) tomorrow.

    • radlad · 40 minutes ago

      Yes, PHP release was scheduled for Wednesday, 21 October 2026 at 14:00 UTC: https://news-web.php.net/php.announce/509

    • bunderbunder · 35 minutes ago

      The official story is that it was originally scheduled for 14:00 UTC tomorrow. Then yesterday they decided to move the date forward by 24 hours in response to information about the vulnerability leaking.

• edaemon · 41 minutes ago

  Even assuming they didn't have prior knowledge, I don't understand why AWS is going to take 24+ hours to incorporate an upstream fix.

  • otterley · 26 minutes ago

    Probably because it takes time for them to run all the regression tests. They don't want to break something while fixing something else. Damned either way. In the meantime, you can mitigate the vulnerability significantly by following the instructions here: https://www.abstract.security/blog/php2shell-critical-php-rc...

Honest question: Does anyone actually use Amazon Linux in production? Everywhere I've every worked used a mainstream distro for cloud servers, like Debian, Ubuntu, Red Hat or SUSE.

• otterley · 52 minutes ago

  I do. It works fine, particularly if you're using EKS- or ECS-optimized images.

• iririririr · 23 minutes ago

  aren't everyone using lambda functions? and aws infra itself? they migth only consider the urgency of internal teams, so anything !java will be pushed.

• benjaopazoc · 21 minutes ago

  We did, until this morning

sounds like they are trying to get rid of users of Amazon Linux honestly
