Thelia v2.6.1 contains path traversal and PHP code injection vulnerabilities in its translation editor that can be chained to achieve remote code execution.
Published Oct 12, 2026 · updated Oct 15, 2026 · CERT/CC
Thelia v2.6.1 contains path traversal and PHP code injection vulnerabilities in its translation editor that can be chained to achieve remote code execution. The parameter, used to build the translation file's write path, does not sanitize directory traversal sequences such as . This enables an authenticated user with -level permissions on to write files outside the expected directory, including to web‑accessible paths. Separately, the translation‑writing logic does not escape in user‑supplied values, allowing inputs to break out of the PHP string literal and inject executable code into the translation file. Chained together, these flaws allow a malicious PHP file to be written to a web-accessible path and executed with the web‑server’s privileges.

Detected
Overview Thelia versions 2.6.0 and 2.6.1 contain multiple vulnerabilities relating to file management, Smarty templating, module installation, and administrative workflows. Successful exploitation of these issues could enable remote code execution (RCE), server-side template injection (SSTI), stored and reflected cross-site scripting (XSS), unauthorized URL redirection, and other risks that expose
