{"cve":"CVE-2026-104198","nvd":{"published":"2026-10-15T20:17:06.127","modified":"2026-10-15T21:17:02.680","status":"Deferred","description":"ZoneMinder is a free, open source closed-circuit television software application. In versions 1.34.0 through 1.36.38, the web interface mishandles failed token authentication in web/includes/auth.php. validateToken() returns false when a token is malformed or has an invalid signature, but the caller assigns that value to the global $user variable; because web/index.php tests isset($user), boolean false is treated as a present user and the normal login redirect is skipped. This can dispatch views that rely on the outer authentication gate, including the zones view, which accepts an attacker-selected monitor ID and discloses monitor and zone metadata without an independent permission check. Permission helpers receive the false user value and deny privileged operations, so unauthorized state changes have not been established. This vulnerability is fixed in version 1.36.63, where conversion to ZM\\User objects causes invalid token state to fail before view dispatch. Later defense-in-depth changes explicitly leave $user unset after failed token validation and reject non-ZM\\User values at the web authentication gate.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-287","CWE-697"],"references":["https://github.com/ZoneMinder/zoneminder/commit/144a04ca4fff5fd02745ce8afc239ba5e05cf8ac","https://github.com/ZoneMinder/zoneminder/commit/6b94903e634fdb46cb71a48eadccf1aa14f0c2bb","https://github.com/ZoneMinder/zoneminder/commit/71bb186b230dbe2aba5e2f804c36810aae892088","https://github.com/ZoneMinder/zoneminder/commit/95460a945ab7e5c63dc0551bdd6230a3026ceb9e","https://github.com/ZoneMinder/zoneminder/commit/969baa38912018b502617d09e836d0bfa57d4af6"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-104198","score":0.00386,"percentile":0.32446,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
