The interim CVE-2026-109618 mitigation lived in the shared hardening.ini, so every PHP role ran without a memory limit until the last image was patched, and no role's service_memory_mb share applied. Registry metadata of the images pinned on main shows that 16 of the 20 consumers already ship PHP 8.2.35, 8.3.36, 8.4.27 or 8.5.12 (or the Alpine/Debian build of it). Four predate the fix: markoshust/magento-php:8.4-fpm (8.4.21), ghcr.io/heviat/webmail:2024.06 (the Mailu OIDC flavor, built 2025-04-04), phpldapadmin/phpldapadmin:2.3.11 (built 2026-05-15) and ghcr.io/shopware/docker-base:8.3 (8.3.25). - Move memory_limit = -1 into its own content-addressed ini (FILE_PHP_MEMORY_UNLIMITED_INI) and mount it only in magento, mailu, phpldapadmin and shopware. - hardening.ini keeps expose_php, session.upload_progress.enabled and fatal_error_backtraces as permanent hardening. - Joomla's php-upload.ini loads as conf.d/uploads.ini again: no -1 has to be outranked anymore. - The root TODO names the four images that still need the override.

# sys-svc-compose-php
|
|
|
|
## Description
|
|
|
|
Internal helper role that installs the shared PHP hardening assets on the
|
|
stack host. PHP services of Docker Compose and Swarm stacks mount them as
|
|
configs from their own `meta/volumes.yml`.
|
|
|
|
## Overview
|
|
|
|
This role installs one PHP ini (`FILE_PHP_HARDENING_INI`), one interim PHP ini
|
|
(`FILE_PHP_MEMORY_UNLIMITED_INI`) and one PHP-FPM pool drop-in
|
|
(`FILE_PHP_FPM_HARDENING_CONF`). A PHP role opts in by declaring a
|
|
`type: config` entry with that file as `source` and a file inside the scan dir
|
|
of its image as `target`, e.g. `conf.d/zz-infinito-hardening.ini` or, for the
|
|
pool, `php-fpm.d/zz-infinito-hardening.conf`. Only roles whose image still
|
|
ships a PHP release without the CVE-2026-109618 fix also mount
|
|
`FILE_PHP_MEMORY_UNLIMITED_INI`, as `conf.d/zz-infinito-memory-unlimited.ini`.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places sys-svc-compose-php in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.
|
|
|
|
## Features
|
|
|
|
- **PHP ini hardening:** `expose_php` off; `session.upload_progress.enabled = 0` and, on PHP 8.5 only, `fatal_error_backtraces = 0` against CVE-2026-109619.
|
|
- **Interim CVE-2026-109618 mitigation:** `memory_limit = -1` for images that predate PHP 8.2.35, 8.3.36, 8.4.27 and 8.5.12.
|
|
- **PHP-FPM worker recycling:** `pm.max_requests` from `PHP_FPM_MAX_REQUESTS` for images whose `[www]` pool reads `php-fpm.d/*.conf`.
