Machine-written summary

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

Jenkins Assembla Plugin version 1.4 and earlier has an HTTP endpoint that tests the connection to an Assembla server and lacks a permission check. An attacker with Overall/Read permission can make Jenkins connect to an attacker-specified URL using an attacker-specified username and password, and the endpoint also accepts requests that are not POST, so it is open to cross-site request forgery. No fix is listed.
