CVE-2026-109397Thelia before 3.1.2 and 3.2.x before 3.2.1 File Upload RCE via Filename Trailing Space

Beschreibung

Thelia before 3.1.2 and 3.2.x before 3.2.1 contains an unrestricted file upload vulnerability that allows authenticated back-office users to upload PHP files by appending a trailing space to filenames. FileProcessorService validates the raw filename but FileManager::sanitizeFileName() strips the space, storing an executable .php file under public/cache/documents/ for code execution as the web server user.
