CVE-2025-6429: 3 source package rows (firefox, firefox-esr, thunderbird); 372 state rows across 2 repos (3.22-community, edge-community); fixed 0, open 372.
Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the URL specified in an `embed` tag. This could have bypassed website security checks that restricted which domains users were allowed to embed. This vulnerability was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12.
