# WordPress Injection Guard plugin: CSRF leaks customer password hashes

Link for people: https://infrastack.ai/live/CVE-2026-127216 (this .md is for agents)

The Injection Guard WordPress plugin before 1.4.0 has a cross-site request forgery flaw in its admin dashboard that lets an attacker trick a logged-in administrator into triggering a password hash export. The export is written to a publicly downloadable file, so an attacker can obtain WooCommerce customer password hashes and crack them offline.

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

## How to check

- Check the installed version of the Injection Guard plugin in the WordPress admin plugins list; versions below `1.4.0` are affected.
- Look for the file `wp-content/plugins/injection-guard/ab-hash.dat` on the web server; if it exists and is reachable over HTTP, customer hashes may already be exposed.

## Fix

- Injection Guard plugin: upgrade to `1.4.0` or later.

## Timeline

## From the sources

Injection Guard plugin for WordPress before 1.4.0 contains a cross-site request forgery vulnerability that allows unauthenticated attackers to trigger password hash export by tricking a logged-in administrator into loading a crafted link, since the ig_settings admin page in templates/dashboard.php processes GET parameters without nonce verification. Attackers can exploit this to cause the plugin to write WooCommerce customer email hashes and password hashes to an unprotected file at wp-content/plugins/injection-guard/ab-hash.dat, which can then be downloaded without authentication to obtain customer password hashes for offline cracking.
