Attackers can access any file readable by the process and the file metadata is written to a persistent cache file with insufficient permissions, creating a forensic record of accessed paths that survives process exit.\n\n## Affected\n\n- `claude-hud <= 0.0.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":18,"depthScoreParts":{"impact":18.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
