SCA: security update for symfony/monolog-bridge, symfony/symfony (GHSA-m7v2-7gxm-vc2v)
high Tenable Self-Hosted Container Security Plugin ID 442403
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to
5.4.52, 6.4.40, 7.4.12, and 8.0.12, the server:log listener
(Symfony\Bridge\Monolog\Command\ServerLogCommand) binds to 0.0.0.0:9911 by default and processes each
received frame with unserialize(base64_decode($message)) without authentication, integrity checks, or an
allowed_classes allowlist, allowing any reachable host to submit attacker-chosen serialized PHP payloads
that can crash the listener and may trigger object-injection gadget effects. This issue is fixed in
versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12. (CVE-2026-45077)
Solution
Update the symfony/monolog-bridge library and its related packages to version 5.4.52 or later.See Also
