What is CVE-2025-43916?
CVE-2025-43916 is a low-severity vulnerability in api.sonos.com, published on 21 Apr 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
Sonos api.sonos.com through 2025-04-21, when the /login/v3/oauth endpoint is used, accepts a redirect_uri containing userinfo in the authority component, which is not consistent with RFC 6819 section 5.2.3.5.
