Prior to 2.4.16.11, a bug in a mod_auth_openidc results in disclosure of protected content to unauthenticated users. The conditions for disclosure are an OIDCProviderAuthRequestMethod POST, a valid account, and there mustn\u0026apos;t be any application-level gateway (or load balancer etc) protecting the server. When you request a protected resource, the response includes the HTTP status, the HTTP headers, the intended response (the self-submitting form), and the protected resource (with no headers). This is an example of a request for a protected resource, including all the data returned. In the case where mod_auth_openidc returns a form, it has to return OK from check_userid so as not to go down the error path in httpd. This means httpd will try to issue the protected resource. oidc_content_handler is called early, which has the opportunity to prevent the normal output being issued by httpd. oidc_content_handler has a number of checks for when it intervenes, but it doesn\u0026apos;t check for this case, so the handler returns DECLINED. Consequently, httpd appends the protected content to the response. The issue has been patched in mod_auth_openidc versions \u0026gt;= 2.4.16.11.(CVE-2025-31492)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP3","name":"mod_auth_openidc","purl":"pkg:rpm/openEuler/mod_auth_openidc\u0026distro=openEuler-22.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.16.11-1.oe2203sp3"}]}],"ecosystem_specific":{"aarch64":["mod_auth_openidc-2.4.16.11-1.oe2203sp3.aarch64.rpm","mod_auth_openidc-debuginfo-2.4.16.11-1.oe2203sp3.aarch64.rpm","mod_auth_openidc-debugsource-2.4.16.11-1.oe2203sp3.aarch64.rpm"],"src":["mod_auth_openidc-2.4.16.11-1.oe2203sp3.src.rpm"],"x86_64":["mod_auth_openidc-2.4.16.11-1.oe2203sp3.x86_64.rpm","mod_auth_openidc-debuginfo-2.4.16.11-1.oe2203sp3.x86_64.rpm","mod_auth_openidc-debugsource-2.4.16.11-1.oe2203sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2025-1442"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-31492"}],"database_specific":{"severity":"High"}}
