GitHub AdvisoriesGHSA-p4wr-9wfm-f9jw
Jenkins SAML Single Sign On(SSO) Plugin missing permission check
Jenkins SAML Single Sign On(SSO) Plugin 2.3.0 and earlier does not perform a permission check in an HTTP endpoint.
This allows attackers with Overall/Read permission to download a string representation of the current security realm (Java Object#toString()), which potentially includes sensitive information.
SAML Single Sign On(SSO) Plugin 2.3.1 requires Overall/Administer permission to access the affected HTTP endpoint, and only allows downloading a string representation if the current security realm is this plugin’s.
