CVE-2026-84203
Memos versions 0.26.0 through 0.30.0 fail to revoke refresh tokens when a user changes their password, allowing attackers to maintain account access. An attacker with a stolen refresh token can call the RefreshToken RPC to obtain new access tokens and rotate the refresh token indefinitely, bypassing the password change security measure.
