Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Archiving multiple files allows directory traversal if paths are not canonicalized and checked against a strict base-directory prefix before being appended. Attackers could potentially read sensitive files outside the intended directory.
Cryptographic Issues: Misusing AEAD encryption for generating metadata signatures can allow signature bypass or integrity compromise. The project had to transition to proper HMAC-SHA256 signature verification to enforce metadata integrity.
Information Disclosure: Automatically shortening URLs via third-party services leaks secret download links to external systems without explicit user consent.
