{"id":"CVE-2026-115513","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-115513","summary":"OpenCATS before 0.12.0 Stored XSS via MRU Navigation Panel","details":"OpenCATS before 0.12.0 contains a stored cross-site scripting vulnerability that allows a low-privileged authenticated user to inject HTML/JavaScript payloads by setting a Candidate, Company, Contact, Job Order, or List name/title field, which is stored unsanitized and later rendered unescaped in the 'Recent' (MRU) navigation panel displayed on nearly every page via lib/MRU.php's getFormatted() function. 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.","published":"2026-10-22T16:52:10.542Z","modified":"2026-10-23T02:45:54.753572581Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/opencats/OpenCATS/commit/f82e0ee3045845b90b7e111c46f30998496e38a8","label":"opencats/OpenCATS@f82e0ee"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115513.json"},{"type":"PACKAGE","url":"https://github.com/opencats/OpenCATS"},{"type":"REPORT","url":"https://github.com/opencats/OpenCATS/commit/f82e0ee3045845b90b7e111c46f30998496e38a8"},{"type":"REPORT","url":"https://github.com/opencats/OpenCATS/commits/master/lib/MRU.php"},{"type":"FIX","url":"https://github.com/opencats/OpenCATS/releases/tag/v0.12.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115513"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/opencats-before-stored-xss-via-mru-navigation-panel"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-23T02:45:54.753572581Z"}}
