CVE-2026-100709

Froxlor through 2.3.10 stores only a numeric user ID in remembered-2FA tokens panel2fatokens 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...

CVE-2026-100710

Froxlor through 2.3.10 does not filter sensitive columns from API responses: Domains::get, Domains::listing, SubDomains::get, and the admin branch of SubDomains::listing perform a wildcard SELECT over the paneldomains table and return the row unmodified, including the paneldomains.dkimprivkey...

CVE-2026-100711

froxlor versions before 2.3.12 fail to invalidate existing panel sessions, API keys, and 2FA trust cookies when a user password is changed. Attackers holding hijacked sessions, valid API keys, or 2FA trust tokens retain full account access after password rotation, bypassing incident response...
