CVE-2022-26384

Si un atacante pudiera controlar el contenido de un iframe en un espacio aislado con <code>allow-popups</code> pero no con <code>allow-scripts</code>, podría crear un enlace que, al hacer clic, conduciría a Ejecución de JavaScript en violación de la sandbox. Esta vulnerabilidad afecta a Firefox &lt; 98, Firefox ESR &lt; 91,7 y Thunderbird &lt; 91.7.

The Mozilla Foundation Security Advisory describes this flaw as: If an attacker could control the contents of an iframe sandboxed with allow-popups but not allow-scripts, they were able to craft a link that, when clicked, would lead to JavaScript execution in violation of the sandbox.

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the browser UI, bypass security restrictions, obtain sensitive information, or execute arbitrary code. A TOCTOU bug was discovered when verifying addon signatures during install. A local attacker could potentially exploit this to trick a user into installing an addon with an invalid signature.
