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.
AnalysisAI
Path traversal in Claude HUD through version 0.0.12 permits local low-privileged attackers to read arbitrary files by supplying a crafted transcript_path value via stdin JSON, bypassing all path validation. Beyond direct file read access, the application writes file metadata - including the accessed paths - to a persistent cache file with insufficiently restrictive permissions, leaving a forensic record readable by other local users that survives process termination. …
