NVD description

In Thelia v2.6.0, the document upload endpoint properly blocks the upload of executable file types, but the document update endpoint does not perform the same validation. An attacker with administrative Thelia permissions can exploit this vulnerability to upload arbitrary executable files, such as malicious PHP scripts, to achieve remote code execution on the underlying server.
