{"id":"CVE-2025-0672","state":"PUBLISHED","title":"Authentication Bypass in Multiple WSO2 Products via Stale FIDO Credential Association","description":"An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not automatically remove associated FIDO registration data. If a new user account is later created using the same username, the system may associate the new account with the previously registered FIDO device.\n\nThis flaw may allow a previously deleted user to authenticate using their FIDO credentials and impersonate the newly created user, resulting in unauthorized access. The vulnerability applies only to deployments that utilize FIDO-based authentication.","publishedAt":"2025-09-23T17:30:42.687Z","updatedAt":"2025-09-25T16:01:00.676Z","severity":{"score":3.3,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N","source":"WSO2"},"assigner":"WSO2","products":["WSO2 WSO2 Identity Server as Key Manager","WSO2 WSO2 Identity Server","WSO2 WSO2 Open Banking IAM"],"affected":[{"vendor":"WSO2","product":"WSO2 Identity Server as Key Manager","defaultStatus":"unaffected","versions":[{"version":"0","status":"unknown","lessThan":"5.10.0","versionType":"custom"},{"version":"5.10.0","status":"affected","lessThan":"5.10.0.338","versionType":"custom"}]},{"vendor":"WSO2","product":"WSO2 Identity Server","defaultStatus":"unaffected","versions":[{"version":"0","status":"unknown","lessThan":"5.10.0","versionType":"custom"},{"version":"5.10.0","status":"affected","lessThan":"5.10.0.345","versionType":"custom"},{"version":"5.11.0","status":"affected","lessThan":"5.11.0.394","versionType":"custom"}]},{"vendor":"WSO2","product":"WSO2 Open Banking IAM","defaultStatus":"unaffected","versions":[{"version":"2.0.0","status":"affected","lessThan":"2.0.0.389","versionType":"custom"}]}],"references":["https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2025/WSO2-2025-3134/"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:08:20.985Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/0xxx/CVE-2025-0672.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-0672","state":"PUBLISHED","datePublished":"2025-09-23T17:30:42.687Z","dateUpdated":"2025-09-25T16:01:00.676Z","assignerShortName":"WSO2","assignerOrgId":"ed10eef1-636d-4fbe-9993-6890dfa878f8","dateReserved":"2025-01-23T13:38:31.988Z"},"containers":{"cna":{"title":"Authentication Bypass in Multiple WSO2 Products via Stale FIDO Credential Association","descriptions":[{"lang":"en","value":"An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled.
