Although the product did not utilize this data, its acceptance could lead to logging. If a user mistakenly sends sensitive data via URL parameters to any flow, this data could be inadvertently logged in access logs. This has the potential to expose confidential information, compromising the security and privacy of affected systems if the product is used incorrectly. ## Affected - `api_manager >= 3.1.0 < 3.1.0.313` - `api_manager >= 3.2.0 < 3.2.0.406` - `api_manager >= 3.2.1 < 3.2.1.30` - `api_manager >= 4.0.0 < 4.0.0.324` - `api_manager >= 4.1.0 < 4.1.0.185` - `api_manager >= 4.2.0 < 4.2.0.124` - `api_manager >= 4.3.0 < 4.3.0.36` - `api_manager >= 4.4.0 < 4.4.0.2` - `open_banking_am >= 2.0.0 < 2.0.0.363` - `identity_server >= 5.10.0 < 5.10.0.337` - `identity_server >= 5.11.0 < 5.11.0.384` - `identity_server >= 6.0.0 < 6.0.0.213` - `identity_server >= 6.1.0 < 6.1.0.211` - `identity_server >= 7.0.0 < 7.0.0.50` - `identity_server_as_key_manager >= 5.10.0 < 5.10.0.329` - `open_banking_iam >= 2.0.0 < 2.0.0.381` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.3.0 < 6.3.0.18` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.3.11 < 6.3.11.23` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.3.58 < 6.3.58.1` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.5.0 < 6.5.0.5` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.6.0 < 6.6.0.1` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.7.8 < 6.7.8.4` - `org.wso2.carbon.identity.application.authenticator.basicauth >= 6.7.32 < 6.7.32.1` - `org.wso2.carbon.identity.core >= 5.17.5 < 5.17.5.286` - `org.wso2.carbon.identity.core >= 5.17.118 < 5.17.118.11` - `org.wso2.carbon.identity.core >= 5.18.187 < 5.18.187.263` - `org.wso2.carbon.identity.core >= 5.18.248 < 5.18.248.23` - `org.wso2.carbon.identity.core >= 5.23.8 < 5.23.8.189` - `org.wso2.carbon.identity.core >= 5.24.8 < 5.24.8.12` - `org.wso2.carbon.identity.core >= 5.25.92 < 5.25.92.91` - `org.wso2.carbon.identity.core >= 5.25.92 < 5.25.92.118` - `org.wso2.carbon.identity.core >= 5.25.705 < 5.25.705.11` - `org.wso2.carbon.identity.core >= 5.25.713 < 5.25.713.2` - `org.wso2.carbon.identity.core >= 7.0.78 < 7.0.78.27` - `org.wso2.carbon.identity.oauth.common >= 6.4.2 < 6.4.2.142` - `org.wso2.carbon.identity.oauth.common >= 6.4.176 < 6.4.176.20` - `org.wso2.carbon.identity.oauth.common >= 6.4.180 < 6.4.180.8` - `org.wso2.carbon.identity.oauth.common >= 6.8.0 < 6.8.0.40` - `org.wso2.carbon.identity.oauth.common >= 6.9.6 < 6.9.6.16` - `org.wso2.carbon.identity.oauth.common >= 6.11.21 < 6.11.21.44` - `org.wso2.carbon.identity.oauth.common >= 6.13.16 < 6.13.16.6` - `org.wso2.carbon.identity.oauth.common >= 6.13.19 < 6.13.19.2` - `org.wso2.carbon.identity.oauth.common >= 7.0.26 < 7.0.26.18` ## Remediation Follow the instructions given on https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3465/#solution
