Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jenkins core (org.jenkins-ci.main:jenkins-core) versions from 2.529 before 2.541, and versions before 2.528.3, do not mask build authorization tokens shown on the job configuration form. An attacker who can view that form could observe and capture the tokens. Upgrade to Jenkins 2.541 or LTS 2.528.3. The source gives few details on who can view the form.
