CSRF protection tokens for anonymous users did not expire in some circumstances

Jenkins allowed the creation of CSRF tokens without a corresponding web session ID. This is the result of an incomplete fix for SECURITY-626 in the 2019-07-17 security advisory. This allowed attackers able to obtain a CSRF token without associated session ID to implement CSRF attacks with the...

This allowed attackers able to obtain a CSRF token for another user to implement CSRF attacks as long as the victim's IP address remained unchanged. CSRF tokens will now also check the web session ID to confirm th...
