Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins Themis Plugin, versions 1.4.1 and earlier, has an HTTP endpoint that lacks a permission check and does not require POST requests. An attacker with Overall/Read permission can make Jenkins connect to a URL they specify, and a cross-site request forgery attack is also possible against this endpoint. No fix is listed at the time of publication, so no upgrade version is available.
