What is CVE-2026-100712?
CVE-2026-100712 is a high-severity vulnerability in froxlor, published on 26 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
froxlor through 2.3.10 disables a user's two-factor authentication immediately upon an unauthenticated-triggerable GET request to the 2FA management page (e.g. /customer_index.php?page=2fa&action=delete), with no confirmation, re-authentication, or CSRF token. The global CSRF middleware only covers POST/PUT/PATCH/DELETE requests, and the session cookie is set to SameSite=Lax, so a cross-site top-level navigation (link click or redirect) carries the victim's session and silently clears type_2fa/data_2fa. Both the customer and admin 2FA handlers are affected. An attacker who lures a logged-in panel user into following a crafted link reduces that account to password-only authentication, which can be chained with a compromised password for account takeover. Fixed in 2.3.12.
Weakness: CWE-352
