    The package jenkins before version 2.192-1 is vulnerable to multiple
    issues including cross-site request forgery and cross-site scripting.
    Upgrade to 2.192-1.
    # pacman -Syu "jenkins>=2.192-1"
    The problems have been fixed upstream in version 2.192.
    - CVE-2019-10383 (cross-site scripting)
    Jenkins did not properly escape the update site URL in some status
    messages shown in the update center, resulting in a stored cross-site
    scripting vulnerability that is exploitable by administrators and
    affects other administrators.
    - CVE-2019-10384 (cross-site request forgery)
    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 following constraints. The token had to be created for the
    anonymous user (and could only be used for actions the anonymous user
    can perform). The victim’s IP address needed to remain unchanged
    (unless the proxy compatibility option was enabled) The victim must not
    have a valid web session at the time of the attack. CSRF token
    generation now creates a web session if none exists yet, so that the
    lack of a web session ID cannot be exploited.
    An attacker with administrative access can execute XSS attacks on other
    administrators by using crafted status messages on the update center.
    Further, an attacker is able to execute a CSRF attack under a very
    narrow set of constraints.
