Because Firefox did not implement the <code>unsafe-hashes</code> CSP
directive, an attacker who was able to inject markup into a page otherwise
protected by a Content Security Policy may have been able to inject
executable script. This would be severely constrained by the specified
Content Security Policy of the document. This vulnerability affects Firefox
< 108.
