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.","categories":["Unclassified"],"product":"OpenCATS","vendor":"opencats","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115513","source_modified_at":"2026-10-23T13:28:36.941Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"OpenCATS","vendor":"opencats","versions":[{"status":"affected","version":"0.10.0","versionType":"semver","lessThan":"0.12.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115513","source_modified_at":"2026-10-23T13:28:36.941Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"OpenCATS","ecosystem":null},"version":"0.12.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00236,"percentile":0.1384,"score_date":"2026-10-23"},"published_at":"2026-10-22T16:52:10.542Z","modified_at":"2026-10-23T13:28:36.941Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115513","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T13:28:36.941Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-115513","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/opencats/OpenCATS/commit/f82e0ee3045845b90b7e111c46f30998496e38a8","tags":["issue-tracking","patch"]},{"source":"CVE List","url":"https://github.com/opencats/OpenCATS/commits/master/lib/MRU.php","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/opencats/OpenCATS/releases/tag/v0.12.0","tags":["patch","release-notes"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/opencats-before-stored-xss-via-mru-navigation-panel","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T13:28:36.941Z","content_hash":"3299d8095fc47143ce39d8ac47d5f63038cacea1c022f9bfd80ee005e722c77c"}}
