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.","published":"2026-05-18T20:16:40.000Z","lastModified":"2026-10-26T13:10:00.000Z","status":"Analyzed","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":4.8,"severity":"MEDIUM","vector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-22"],"affected":["jarrodwatts/claude hud"],"epss":{"score":0.00126,"percentile":0.02275,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.13%).
