This security bulletin contains information about 1 vulnerability.


1) Authentication Bypass by Assumed-Immutable Data (CVE-ID: CVE-2026-28510)

CWE-ID: CWE-302 - Authentication Bypass by Assumed-Immutable Data

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to bypass multi-factor authentication and gain unauthorized account access.

The vulnerability exists due to authentication bypass by assumed-immutable data in the login flow when processing attacker-controlled TOTP secret data. A remote privileged user can use valid primary credentials and complete authentication without the additional factor to bypass multi-factor authentication and gain unauthorized account access.

Multi-factor authentication may not be enforced even when enabled under certain conditions.
