CVE-2026-107335

Malcolm's upload-processing pipeline scripts/safe-extract.py enforces entry-count, nesting-depth, and total-uncompressed-byte limits when extracting container archives zip/tar/rar/7z via libarchive, but those limits are not applied when the uploaded file is a single-stream compressed format .gz,...

CVE-2026-107334

The Malcolm software contains an Incorrect Authorization vulnerability in its nginx Lua role-based access control (RBAC) layer.

Nginx itself, however, selects...
