PHP2Shell in GLPI: is it affected and how to fix it

How to check the PHP version GLPI uses

Run the command for your setup. A version at or above 8.2.35, 8.3.36, 8.4.27 or 8.5.12 in its branch is fixed; older branches are fixed only by a vendor build that says so.

php -v
docker exec <glpi> php -v

The command-line php can differ from the PHP that serves the site. To be sure, check the web SAPI (a temporary phpinfo() page behind authentication, or the panel's PHP settings) and remove it afterwards. Our version checker compares a version number for you.

How to fix PHP2Shell in GLPI

Find out where the PHP that runs this application comes from: your distribution, a third-party repository (Ondřej Surý, Remi), a hosting panel, a Docker image or your host.
Update that PHP to 8.2.35, 8.3.36, 8.4.27, 8.5.12 or a vendor build with the backported fix, and restart every PHP worker.
On shared or managed hosting you cannot patch PHP yourself: ask the host whether the fixed PHP is deployed, and switch the site to a fixed version in the panel.
If the site still runs PHP 8.1 or older, move it to a supported branch; PHP published only source patches for 7.4, 8.0 and 8.1.

If you cannot patch yet

Set session.upload_progress.enabled = 0 where applications cannot override it (php.ini, php_admin_value in the FPM pool or Apache config), and restart PHP.
On PHP 8.5, set fatal_error_backtraces = 0.
PHP's interim advice also covers memory_limit and a low post_max_size; follow the remediation page exactly, because these settings only reduce some paths.
Restrict access (VPN, IP allowlist) or take the service offline if it runs PHP 8.1 or older with no vendor backport. WAF rules help but are not a fix.

FAQ

Is GLPI affected by PHP2Shell?

Affected until you install the vendor's fixed release. The official GLPI Docker images ship PHP 8.5.12. GLPI installed on a server uses that server's PHP, which you must update.

Does updating GLPI itself fix CVE-2026-109618 and CVE-2026-109619?

Only if the update contains fixed PHP. PHP2Shell is a flaw in the PHP interpreter, so what matters is the PHP that GLPI runs on. Check the version after updating.

Which PHP versions fix PHP2Shell?

PHP 8.2.35, 8.3.36, 8.4.27 and 8.5.12, released 21 October 2026. PHP 8.1 and older get no release from the PHP project; only vendor builds with a backport (or a self-built source patch for 7.4, 8.0 and 8.1) fix them.

What if GLPI has no fix yet?

Keep its PHP-based web interface off the internet (VPN or IP allowlist), apply PHP's interim settings such as disabling session upload progress, and install the vendor update as soon as it ships. Interim settings reduce risk but are not a fix.
