Stored XSS vulnerability in Jenkins Extra Columns Plugin
Jenkins Extra Columns Plugin 1.22 and earlier does not escape parameter values in the build parameters column.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission. Additionally, a view containing such a job needs to be configured with the build parameters column, or the attacker also needs View/Configure permission.
Jenkins Extra Columns Plugin 1.23 escapes parameter values in the build parameters column.
