Attackers can exploit this by crafting a malicious record name that executes arbitrary JavaScript in the session of any other user, including Site Administrators, who views the record, enabling session/cookie theft and privilege escalation to full administrative control.","epss":{"date":"2026-11-04","percentile":0.22405,"score":0.00296},"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","version":"4.0"},{"score":8.7,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"}],"modifiedAt":1793820538659,"publishedAt":1792687930542,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/opencats/OpenCATS/commit/f82e0ee3045845b90b7e111c46f30998496e38a8"},{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/opencats/OpenCATS/commits/master/lib/MRU.php"},{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://github.com/opencats/OpenCATS/releases/tag/v0.12.0"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/opencats-before-stored-xss-via-mru-navigation-panel"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
