Description

Jenkins Claim Plugin 2.18.1 and earlier does not escape the user display name shown in claims.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers who are able to control the display names of Jenkins users, either via the security realm, or directly inside Jenkins.

Everyone with a Jenkins account can change their own display name.\n\nClaim Plugin 2.18.2 escapes the user display name shown in claims.
