Descriptions

Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the tooltip content of help icons, resulting in a stored cross-site scripting (XSS) vulnerability.

Jenkins versiones 2.251 y anteriores, versiones LTS 2.235.3 y anteriores, no escapan el contenido de tooltip de los iconos de ayuda, resultando en una vulnerabilidad de tipo cross-site scripting (XSS) almacenado

A flaw was found in Jenkins in versions prior to 2.251 and LTS 2.235.3. Tooltip values, which are not properly escaped, can be contributed by plugins and use user-specified values. This results in a potential stored cross-site scripting (XSS) vulnerability. This highest threat from this vulnerability is to data confidentiality and integrity.

Jenkins version 2.235.3 suffers from multiple persistent cross site scripting vulnerabilities.
