CVE-2026-55878 · Symfony: Path Traversal in symfony/ux-toolkit Allows Arbitrary File Write and Read via Crafted Recipe Manifest

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Symfony UX is a JavaScript ecosystem for Symfony. From 2.32.0 before 2.36.1 and from 3.0.0 before 3.2.0, the ux:install console command installs files from a recipe kit by copying paths listed in a copy-files map, and because Path::isRelative() accepts paths like ../../../etc, a crafted or compromised kit can write attacker-controlled content to arbitrary locations or read local files outside the recipe directory. This issue is fixed in versions 2.36.1 and 3.2.0.
