Exploitation Probability (EPSS)

Elevated risk
0.90%

58th percentile - higher than 58% of all known CVEs

Summary

Papermerge 3.5.3 allows remote code execution by a standard user via directory traversal in a /api/documents/upload call. A Python .pth file can be written to site-packages, and its code is executed upon the next start of the Python interpreter.

Risk Assessment

An authenticated low-privileged user can achieve code execution on the server, leading to full system compromise and data access.

Recommendation

Update Papermerge to a version later than 3.5.3, and until then restrict access to the upload API and monitor the site-packages directory for unauthorized .pth files.
