CVSS: 6.1EPSS: 1%CPEs: 3EXPL: 0CVE-2020-6798 – Mozilla: Incorrect parsing of template tag could result in JavaScript injection
https://notcve.org/view.php?id=CVE-2020-6798
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. Si se usó una etiqueta template en una etiqueta select, el analizador podría ser confundido y permitir el análisis y la ejecución de JavaScript cuando no debería ser permitido. • https://bugzilla.mozilla.org/show_bug.cgi?id=1602944 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4278-2 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://www.mozilla.org/security/advisories/mfsa2020-07 https://access.redhat.com/security/cve/CVE-2020-6798 https://bugzilla. • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2019-17022 – Mozilla: CSS sanitization does not escape HTML tags
https://notcve.org/view.php?id=CVE-2019-17022
When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
