CVE-2026-5795
A subsequent request using the same thread inherits the ThreadLocal values, leading to a broken access control and privilege escalation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
