https://notcve.org/view.php?id=CVE-2022-22759
If a document created a sandboxed iframe without <code>allow-scripts</code>, and subsequently appended an element to the iframe's document that e.g. had a JavaScript event handler - the event handler would have run despite the iframe's sandbox. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. Si un documento creó un iframe en la sandboxed sin <code>allow-scripts</code> y posteriormente agregó un elemento al documento del iframe que, por ejemplo, tenía un controlador de eventos JavaScript, el controlador de eventos se habría ejecutado a pesar de la sandbox del iframe. Esta vulnerabilidad afecta a Firefox < 97, Thunderbird < 91.6 y Firefox ESR < 91.6. The Mozilla Foundation Security Advisory describes this flaw as: If a document created a sandboxed iframe without allow-scripts and subsequently appended an element to the iframe's document that, for example, had a JavaScript event handler - the event handler would have run despite the iframe's sandbox. • https://bugzilla.mozilla.org/show_bug.cgi?id=1739957 https://www.mozilla.org/security/advisories/mfsa2022-04 https://www.mozilla.org/security/advisories/mfsa2022-05 https://www.mozilla.org/security/advisories/mfsa2022-06 https://access.redhat.com/security/cve/CVE-2022-22759 https://bugzilla.redhat.com/show_bug.cgi?id=2053242 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
