When a pages content security policy (CSP) header contains a sandbox directive, other directives are ignored. This results in the incorrect enforcement of CSP. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
