## Overview

Craft Commerce’s `ProductQuery::hasVariant` and `VariantQuery::hasProduct` properties bypass the `unset()` blocklist added to `ElementIndexesController` in GHSA-2453-mppf-46cj.

The blocklist only strips top-level Yii2 Query properties (`where`, `orderBy`, etc.), but `hasVariant` and `hasProduct` pass through untouched. Internally, these properties call `Craft::configure()` on a subquery without sanitization, re-introducing SQL injection via `criteria[hasVariant][where]=INJECTED_SQL`.

An authenticated control panel user can perform boolean-based blind SQL injection through the patched `ElementIndexesController` and extract arbitrary database contents.

## Impact

* Full database read access via blind SQL injection * Privilege escalation via security key extraction → forged admin sessions

## Prerequisites * Authenticated control panel user * Commerce plugin installed * Products with variants in the database
