Summary

Thelia versions up to and including 2.6.0 accept module ZIP uploads without validating or sandboxing embedded PHP code (CWE-434).

Description from the CNA

Thelia v2.6.0 permits authenticated administrators to upload and install modules via the ZIP upload function without validating or sandboxing embedded PHP code. An attacker can include malicious PHP code in a module's `install()` method which will then be executed upon installation, enabling remote code execution with the privileges of the web server.
