CVE-2022-33012Public exploitNetwork attack vector

Account takeover via poisoned password-reset links

Published Nov 22, 2022 · Updated Apr 29, 2025

Host header injection in Microweber 1.2.15 and earlier allows remote attackers to take over accounts through password reset poisoning. The password-reset flow uses the untrusted HTTP Host header to build the emailed reset URL, so following it sends a valid reset token to an attacker-controlled host. Exploitation requires the targeted user to follow the poisoned link; possession of the token permits the attacker to reset that account's password.
