CVE-2026-43911
Description
A flaw was found in Vaultwarden. This vulnerability allows an attacker who has previously obtained a user's refresh token to maintain session access. This occurs because refresh tokens are not invalidated when security-sensitive operations, such as password changes or key rotations, are performed. Consequently, an attacker can continue to access a user's account even after the user has attempted to secure it, leading to unauthorized access.
