Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Path traversal vulnerabilities allowed arbitrary file access and validation bypasses via uncanonicalized paths in server endpoints like the add_from_file tool. Ensuring absolute normalization prior to checking file properties is critical to secure these interfaces.
SSRF: The open-access PDF download tool was vulnerable to Server-Side Request Forgery. It required the implementation of strict DNS resolution validation and manual tracking of redirect hops to prevent internal network scanning.
Path Traversal: Archive extraction operations on downloaded utilities were vulnerable to Arbitrary File Write/Path Traversal via malicious tarfile or zipfile entries. The extraction pipeline requires verification that member paths stay strictly within the target destination.
