What is CVE-2026-92127?

The Jenkins Script Security Plugin prior to version 1415.v9a_f9b_3a_c253d allows users with Overall/Administer privileges to inadvertently approve classpath entries when copying or updating item configurations via the REST API or CLI.

Immediate action is recommended to mitigate potential attacks.
