CVE-2023-41900

Summary

CVE-2023-41900 is a vulnerability affecting Jetty, a Java web server and servlet engine. Versions 9.4.21 through 11.0.15 are vulnerable, specifically when using the `OpenIdAuthenticator` with a nested `LoginService`. If the `LoginService` revokes authentication for a user, the current request will still consider the user as authenticated, allowing unauthorized access. Subsequent requests will not be treated as authenticated, creating a potential security risk. The vulnerability can be exploited in usages of jetty-openid with a nested `LoginService` that is capable of rejecting previously authenticated users. Versions 9.4.52, 10.0.16, and 11.0.16 have been patched to address this issue.
