Detailsinfo

A vulnerability was found in jarrodwatts claude-hud up to 0.0.12. It has been classified as problematic. Affected is some unknown functionality. The manipulation of the argument transcript_path with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:

Claude HUD through 0.0.12, patched in commit 234d9aa, contains a path traversal vulnerability that allows attackers to read arbitrary files by supplying an unvalidated transcript_path value via stdin JSON. 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.

The weakness was released by Katriel Moses as 485. The advisory is available at github.com. This vulnerability is traded as CVE-2026-47091 since 05/18/2026. The exploitability is told to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Applying the patch 234d9aad919b51326a43bcf90b45ae35c23afc30 is able to eliminate this problem. The bugfix is ready for download at github.com.
