Jenkins Folder-based Authorization Strategy Plugin 217.vd5b_18537403e and earlier does not verify that permissions configured to be granted are enabled, potentially allowing users formerly granted (typically optional permissions, like Overall/Manage) to access functionality they're no longer entitled to.

Jenkins Folder-based Authorization Strategy Plugin 1.3 and earlier does not escape the names of roles shown on the configuration form, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.
