Event handlers on "marquee" elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript.

MEDIUM 6.1EPSS 1.84%

Does this matter?

Lower severity and a low EPSS score (1.84%). Track it; it rarely justifies an emergency change on its own.

Description

Event handlers on "marquee" elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
