Hi,

The following vulnerability was published for jetty.

CVE-2026-5795[0]:
| In Eclipse Jetty, the class JASPIAuthenticator initiates the
| authentication checks, which set two ThreadLocal variable.   Upon
| returning from the initial checks, there are conditions that cause
| an early return from the JASPIAuthenticator code without clearing
| those ThreadLocals.   A subsequent request using the same thread
| inherits the ThreadLocal values, leading to a broken access control
| and privilege escalation.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
