Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins GitHub Plugin (Maven com.coravy.hudson.plugins.github:github) versions before 1.46.0.1 are affected by a stored cross-site scripting flaw in the JavaScript that validates the "GitHub hook trigger for GITScm polling" feature, which improperly processes the current job URL. An attacker with Overall/Read permission, who is not anonymous, can exploit this. Upgrade to version 1.46.0.1, which no longer processes the job URL in that validation code.
