Prior to version 1.11.1, mod_verto's check_auth userauth branch wrote request-supplied userVariables into the connection state before comparing the supplied password. The writes are append-only and the connection is not closed on a failed compare, so values declared on bad-password attempts persisted on the same WebSocket and carried into a subsequent successful login on that connection. This issue has been patched in version 1.11.1."}], "lastModified": "2026-06-10T15:06:53.767", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:freeswitch:freeswitch:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E8AED0D0-D5A1-4AA1-9CAE-13830B74CAC5", "versionEndExcluding": "1.11.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
