Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2017-7803
CWEhttps://cwe.mitre.org/data/definitions/269.html

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.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
