CyberRota Analysis

AI-Generated

Versions 0.26.0 to 0.30.0 of Memos are vulnerable due to inadequate revocation of refresh tokens upon password changes, allowing attackers to retain access even after a password update. This flaw enables an attacker with a stolen refresh token to continuously generate new access tokens, undermining the intended security of the password change process. Organizations using these Memos versions should prioritize immediate remediation to prevent unauthorized account access.

Original NVD Description

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.
