What is CVE-2025-23086?
CVE-2025-23086 is a medium-severity vulnerability in Brave Desktop Browser, published on 21 Jan 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
On most desktop platforms, Brave Browser versions 1.70.x-1.73.x included a feature to show a site's origin on the OS-provided file selector dialog when a site prompts the user to upload or download a file. However the origin was not correctly inferred in some cases. When combined with an open redirector vulnerability on a trusted site, this could allow a malicious site to initiate a download whose origin in the file select dialog appears as the trusted site which initiated the redirect.
Weakness: CWE-601
