Overview

CVE-2026-100709 is a high-severity vulnerability. It was published on September 26, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Froxlor through 2.3.10 stores only a numeric user ID in remembered-2FA tokens (panel_2fa_tokens) without recording the account namespace, and the remembered-token lookup during login is not constrained to the customer or administrator account type. Because customer and administrator IDs are allocated from separate namespaces, a remembered-2FA token legitimately issued to a customer with a given ID also matches an administrator with the same ID. An attacker who controls a customer account with a colliding ID, holds a valid remembered-2FA cookie for it, and already knows the target administrator's password can bypass the administrator's TOTP second factor and obtain an authenticated administrator session. This is a second-factor bypass only; it does not defeat password authentication. Fixed in 2.3.11.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
