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.
