🛡️ Sentinel: [CRITICAL] Fix path traversal in file upload - #220

Conversation
- Identified path traversal vulnerability in `save_uploaded_file_temp` where `uploadedfile.name` was used directly in `os.path.join`. - Fixed by wrapping `uploadedfile.name` with `os.path.basename()` to sanitize the filename and prevent writing files outside the intended temporary directory. - Documented vulnerability and learning in Sentinel journal.

🚨 Severity: CRITICAL
💡 Vulnerability: The
save_uploaded_file_tempmethod inlibs/general_utils.pydirectly used the user-provideduploadedfile.nameinos.path.joinwithout sanitization, creating a path traversal vulnerability.🎯 Impact: Attackers could supply filenames containing directory traversal characters (e.g.,
../../../etc/passwd), allowing them to write files outside the intendedtempDir, potentially overwriting critical system files or executing arbitrary code.🔧 Fix: Sanitized the user-provided filename using
os.path.basename()before passing it toos.path.join().✅ Verification: Ran
python3 -m py_compile script.py libs/*.pyto ensure syntax integrity. Evaluated the fix logically to confirm path traversal payloads are now properly stripped to just the filename.PR created automatically by Jules for task 10439809140845512023 started by @haseeb-heaven
