CVE-2023-27898: XSS
First published: Wed Mar 08 2023(Updated: )
A flaw was found in Jenkins. Affected versions of Jenkins do not escape the Jenkins version that a plugin depends on when rendering the error message stating its incompatibility with the current version of Jenkins in the plugin manager. This issue results in a stored Cross-site scripting (XSS) vulnerability, exploitable by attackers able to provide plugins to the configured update sites and have this message shown by Jenkins instances.
