This occurs when the session-bound token feature is enabled with token binding validation and the \"Revoke token upon user logout\" option is not active. The software fails to automatically invalidate session-bound tokens upon user session termination.\n\nThis vulnerability exists when token binding validation is enabled. As a result, a malicious actor possessing a valid session-bound token could exploit this condition to maintain unauthorized access to applications and resources even after the associated user session has ended, potentially leading to the exposure of sensitive user data.\n\n## Affected\n\n- `api_control_plane >= 4.5.0 < 4.5.0.47`\n- `api_control_plane >= 4.6.0 < 4.6.0.13`\n- `universal_gateway >= 4.5.0 < 4.5.0.46`\n- `universal_gateway >= 4.6.0 < 4.6.0.11`\n- `api_manager >= 3.1.0 < 3.1.0.352`\n- `api_manager >= 3.2.0 < 3.2.0.456`\n- `api_manager >= 3.2.1 < 3.2.1.81`\n- `api_manager >= 4.0.0 < 4.0.0.376`\n- `api_manager >= 4.1.0 < 4.1.0.246`\n- `api_manager >= 4.2.0 < 4.2.0.186`\n- `api_manager >= 4.3.0 < 4.3.0.97`\n- `api_manager >= 4.4.0 < 4.4.0.61`\n- `api_manager >= 4.5.0 < 4.5.0.46`\n- `api_manager >= 4.6.0 < 4.6.0.11`\n- `traffic_manager >= 4.5.0 < 4.5.0.45`\n- `traffic_manager >= 4.6.0 < 4.6.0.11`\n- `identity_server_as_key_manager >= 5.10.0 < 5.10.0.372`\n- `open_banking_iam >= 2.0.0 < 2.0.0.421`\n- `open_banking_am >= 2.0.0 < 2.0.0.401`\n- `identity_server >= 5.10.0 < 5.10.0.381`\n- `identity_server >= 5.11.0 < 5.11.0.428`\n- `identity_server >= 6.0.0 < 6.0.0.255`\n- `identity_server >= 6.1.0 < 6.1.0.256`\n- `identity_server >= 7.0.0 < 7.0.0.133`\n- `identity_server >= 7.1.0 < 7.1.0.41`\n- `identity_server >= 7.2.0 < 7.2.0.3`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.2 < 6.4.2.171`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.111 < 6.4.111.165`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.176 < 6.4.176.30`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.180 < 6.4.180.14`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.8.0 < 6.8.0.54`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.9.6 < 6.9.6.29`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.11.21 < 6.11.21.94`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.16 < 6.13.16.21`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.19 < 6.13.19.14`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.27 < 6.13.27.10`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.41 < 6.13.41.1`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 7.0.26 < 7.0.26.87`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 7.0.259 < 7.0.259.34`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 7.0.385 < 7.0.385.3`\n\n## Remediation\n\nFollow the instructions given on https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2025-4727/#solution","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
