Doc Text:
A flaw was found in Jenkins and Jenkins Long-Term Support (LTS), where it could allow a remote, authenticated attacker to bypass security restrictions caused by the inclusion of insufficiently escaped user-provided values in part of the URL. An attacker can send a POST request to an unexpected endpoint by persuading a victim to open a context menu.

Description Guilherme de Almeida Suckevicz 2023-06-14 16:42:52 UTC
In Jenkins 2.399 and earlier, LTS 2.387.3 and earlier, POST requests are sent in order to load the list of context actions. If part of the URL includes insufficiently escaped user-provided values, a victim may be tricked into sending a POST request to an unexpected endpoint by opening a context menu.
