What fixes it

No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.

Description

In Thelia v2.6.0, the store banner upload feature performs insufficient filetype validation that relies exclusively on client‑supplied MIME types. An attacker with administrative access can upload a PHP file disguised as an image to bypass validation and achieve remote code execution on the underlying server.
