CVE-2024-8383 (GCVE-0-2024-8383)

Vulnerability from cvelistv5 – Published: 2024-09-03 12:32 – Updated: 2025-11-04 16:16

Summary
Firefox normally asks for confirmation before asking the operating system to find an application to handle a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an unscrupulous program that the user downloaded could register itself as a handler. The website that served the application download could then launch that application at will. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, and Firefox ESR < 115.15.
