{"id":"CVE-2026-47091","summary":"Claude HUD 0.0.12 Path Traversal via transcript_path","details":"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.","modified":"2026-07-08T08:13:54.254378105Z","published":"2026-05-18T19:45:55.216Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47091.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47091.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47091"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/claude-hud-path-traversal-via-transcript-path"},{"type":"REPORT","url":"https://github.com/jarrodwatts/claude-hud/issues/485"},{"type":"REPORT","url":"https://github.com/jarrodwatts/claude-hud/pull/487"},{"type":"FIX","url":"https://github.com/jarrodwatts/claude-hud/commit/234d9aad919b51326a43bcf90b45ae35c23afc30"},{"type":"PACKAGE","url":"https://github.com/jarrodwatts/claude-hud"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jarrodwatts/claude-hud","events":[{"introduced":"0"},{"fixed":"234d9aad919b51326a43bcf90b45ae35c23afc30"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.0.12"}],"cpe":"cpe:2.3:a:jarrodwatts:claude_hud:*:*:*:*:*:claude_code:*:*","source":["CPE_RANGE","REFERENCES"]}}],"versions":["v0.0.12","v0.0.10","v0.0.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47091.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
