Description Avinash Hanwate 2026-08-05 13:42:41 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

In Eclipse Jetty, an HTTP URI of this form:





/public;/../admin/secret.txt








results in an unresolved path of:





/public/../admin/secret.txt








instead of the expected:





/admin/secret.txt








Jetty itself is not affected, as it will not serve the secret.txt file because it will not pass the alias checker (only resolved resources are served).




However, web applications that rely on resolved paths being provided by Jetty may be confused when receiving an unresolved path.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
