CVE-2022-29933Public exploitNetwork attack vector

Account takeover via trusted X-Forwarded-Host reset links

Published May 9, 2022 · Updated Aug 3, 2024

Password reset poisoning in Craft CMS 3.7.36 and earlier allows remote attackers to take over accounts through a forged reset link. The password-reset email generator trusts the X-Forwarded-Host header when building its absolute link, allowing an arbitrary host to receive valid secret reset tokens. Exploitation requires a known username or email address and a user to click the poisoned link; the exposed tokens let attackers reset that account password and sign in.
