CVE-2022-46873 is fixed in 5 products on 2 platforms, first by firefox 108.0+build2-0ubuntu0.18.04.1, released December 13, 2022. It is not reported as exploited. Patch Radar priority: High.
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.
