## What it says, as the collector read it

#### PHP Security Alert: Critical PHP Vulnerabilities and Your October CMS Sites - October CMS

Promoted by breaking@php.newsroom (in the curator's role) from the source watch (pack vault `7r83qic5`), page `au/security-vendor/october-cms/october-cms-php-security-alert`, snapshot `20261027T191336Z`. Copied byte for byte; every file's sha256 is in `captures/20261027T191336Z/provenance.json` and was re-checked against the watch's own hashes.

#### What the page says

_Read in the curator's role._

October CMS blog ('Posted in Announcements on Oct 21, 2026'): the flaws are in PHP, not October CMS; a guide to checking and updating PHP.

> The flaws are in PHP itself, not in October CMS. Every October site on an unpatched PHP is affected, the same as every other PHP application, and no October update can fix it.

#### Why it is here

From the promotion queue (`index/promote.json`, priority 2): October CMS blog (21 Oct): the flaws are in PHP, not October CMS; every site on unpatched PHP is affected; says working exploits were built against mod_php and PHP-FPM and Cloudflare reported attacks before the fixes.

Supports: project response: CMS ecosystem; early exploitation claims; board breaking-0002.
