# Control Web Panel: password reset host header flaw enables account takeover

Link for people: https://infrastack.ai/live/CVE-2026-124020 (this .md is for agents)

Control Web Panel (CWP) before webpanel_version 1.30.6 builds password-reset links from the HTTP Host header, so an attacker can make a reset link point to their own server. A mail scanner that opens the poisoned link leaks the live recovery token, which lets the attacker set a new password and then run commands as the hosting account through the File Manager and Crontab modules.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed CWP version in the admin panel or the webpanel_version value; versions below `1.30.6` are in the stated range
- Confirm whether the panel is reachable from the internet, since the /v1/lostpass/ route is unauthenticated
- Review web server logs for requests to /v1/lostpass/ with unusual Host headers

## Fix

- Control Web Panel: upgrade to `webpanel_version` `1.30.6` or later

## From the sources

Control Web Panel (CWP) before webpanel_version 1.30.6 contains a host header injection vulnerability that allows unauthenticated attackers to manipulate the password-recovery reset URL by injecting the HTTP Host header into the /v1/lostpass/ route's token generation process. Attackers can lure an automated mail-security scanner into visiting the poisoned reset link to exfiltrate the live recovery token, replay it at /login/index.php?acc=newpass to set a new password, and subsequently abuse the File Manager and Crontab modules to achieve command execution as the targeted hosting account.
