{"id":"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.","modified":"2026-10-23T02:45:54.753572581Z","published":"2026-10-22T16:52:10.542Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115513.json","unresolved_ranges":[{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"0.10.0"},{"fixed":"0.12.0"}],"source":"AFFECTED_FIELD"}]},{"extracted_events":[{"source":"CPE_FIELD","strategy":"CPEApplicability","range":[{"introduced":"0.10.0"},{"fixed":"0.12.0"}]}]},{"extracted_events":[{"range":[{"fixed":"0.12.0"}],"source":"DESCRIPTION"}]}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-79"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opencats/opencats","events":[{"introduced":"0"},{"fixed":"f82e0ee3045845b90b7e111c46f30998496e38a8"},{"fixed":"a37909bea08b5249604e86742023a71638a6d7b5"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"f82e0ee3045845b90b7e111c46f30998496e38a8"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"a37909bea08b5249604e86742023a71638a6d7b5"}],"source":"REFERENCES_TAG","original_tag":"v0.12.0"}]}}],"versions":["v0.11.1","v0.11.0","v0.10.0","0.9.7.4","0.9.7.3","v0.9.7.2","opencats-0.9.7","0.9.6","0.9.4-3","0.9.4-2","0.9.4-1","0.9.4","0.9.3-3","0.9.3-2","0.9.3-1","0.9.1a","opencats-0.9.3(final)","opencats-0.9.3(alpha)","opencats-0.9.3","0.9.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-115513.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
