This weakness allows an attacker to obtain valid access tokens for user accounts even after they have been blocked by the user store, bypassing account lockout mechanisms.\n\nThis vulnerability can lead to unauthorized access to user accounts and their associated resources. Attackers can leverage this to perform actions on behalf of blocked users, potentially leading to privilege escalation or data exfiltration depending on the permissions of the compromised account.\n\n## Affected\n\n- `api_manager >= 3.1.0 < 3.1.0.308`\n- `api_manager >= 3.2.0 < 3.2.0.429`\n- `api_manager >= 3.2.1 < 3.2.1.49`\n- `api_manager >= 4.0.0 < 4.0.0.315`\n- `api_manager >= 4.1.0 < 4.1.0.214`\n- `api_manager >= 4.2.0 < 4.2.0.149`\n- `api_manager >= 4.3.0 < 4.3.0.62`\n- `api_manager >= 4.4.0 < 4.4.0.25`\n- `api_manager >= 4.5.0 < 4.5.0.9`\n- `universal_gateway >= 4.5.0 < 4.5.0.9`\n- `traffic_manager >= 4.5.0 < 4.5.0.9`\n- `api_control_plane >= 4.5.0 < 4.5.0.10`\n- `identity_server_as_key_manager >= 5.10.0 < 5.10.0.324`\n- `identity_server >= 5.10.0 < 5.10.0.331`\n- `identity_server >= 5.11.0 < 5.11.0.376`\n- `identity_server >= 6.0.0 < 6.0.0.219`\n- `identity_server >= 6.1.0 < 6.1.0.205`\n- `identity_server >= 7.0.0 < 7.0.0.73`\n- `open_banking_am >= 2.0.0 < 2.0.0.357`\n- `open_banking_iam >= 2.0.0 < 2.0.0.377`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.2 < 6.4.2.148`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.111 < 6.4.111.122`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.176 < 6.4.176.26`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.4.180 < 6.4.180.10`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.8.0 < 6.8.0.44`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.9.6 < 6.9.6.21`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.11.21 < 6.11.21.64`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.16 < 6.13.16.13`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.19 < 6.13.19.7`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 6.13.27 < 6.13.27.1`\n- `org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.oauth >= 7.0.26 < 7.0.26.37`\n\n## Remediation\n\nFollow the instructions given on https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3676/#solution","depth":"sunlit","depthScore":27,"depthScoreParts":{"impact":27,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
