Soumettre #674145: LearnHouse learnhouse 98dfad76aad70711a8113f6c1fdabfccf10509ca Client-Side Enforcement of Server-Side Securityinformation

TitreLearnHouse learnhouse 98dfad76aad70711a8113f6c1fdabfccf10509ca Client-Side Enforcement of Server-Side Security
DescriptionCertain LearnHouse file upload endpoints enforce file-type checks **only on the client side**. An attacker can upload a benign image to pass client-side checks, intercept the multipart request, and replace the uploaded content with any payload (e.g., SVG, `.py`, `.php`). This allows Stored XSS (via SVG) or arbitrary file storage that may lead to RCE. Affects all versions up to commit `98dfad7`.
