Path Traversal in deepseek-tui (CVE-2026-75914)
Summary
Path traversal in deepseek-tui (CVE-2026-75914). Confidential information can be exposed externally. Exploitable via Authorization header. Mitigation: upgrade to 0.8.41 or later.
Original description
The description as published by the source.
CodeWhale versions before 0.8.64 contain a path traversal vulnerability in the image_analyze tool that fails to canonicalize symlinks before reading files. Attackers can create workspace symlinks pointing to external files with image extensions to leak file bytes to the vision endpoint without user approval.
