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 below 1.625.2, and versions from 1.626 up to but not including 1.640, do not verify checksums for plugin files referenced in update site data. An attacker who can intercept the connection between Jenkins and the update site (a man-in-the-middle position) could serve a crafted plugin and execute arbitrary code. Upgrade to 1.625.2 (LTS) or 1.640 or later.
