What is CVE-2026-26227?
CVE-2026-26227 is a medium-severity authentication bypass vulnerability in VideoLAN VLC for Android, published on 26 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
VideoLAN VLC for Android prior to version 3.7.0 contains an authentication bypass in the Remote Access Server feature due to missing or insufficient rate limiting on one-time password (OTP) verification. The Remote Access Server uses a 4-digit OTP and does not enforce effective throttling or lockout within the OTP validity window, allowing an attacker with network reachability to the server to repeatedly attempt OTP verification until a valid user_session cookie is issued. Successful exploitation results in unauthorized access to the Remote Access interface, limited to media files explicitly shared by the VLC for Android user.
Weakness: CWE-307
