CVE-2024-9394

A flaw was found in Mozilla. The Mozilla Foundation's Security Advisory describes the issue as follows: An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the resource://devtools origin. This could allow them to access cross-origin JSON content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions.

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, obtain sensitive information across domains, or execute arbitrary code. Masato Kinugawa discovered that Firefox did not properly validate javascript under the "resource://pdf.js" origin. An attacker could potentially exploit this issue to execute arbitrary javascript code and access cross-origin PDF content.
