| Titel | Blossom Blossom ≤ 1.17.1 Path Traversal |
|---|
| Beschreibung | A Path Traversal vulnerability exists in Blossom versions 1.17.1 and earlier. The issue is found in the /picture/file/upload endpoint, where user-supplied filenames are concatenated into the filesystem path and processed by the BLOSManager.put() method without proper validation. This allows authenticated attackers to utilize directory traversal sequences (e.g., ../) to write arbitrary files outside the intended upload directory. |
