Unauthenticated database disclosure via unescaped taxonomy names
Published Jul 26, 2021 · Updated Aug 3, 2024
SQL injection in WooCommerce Blocks 2.5.0 through 2.5.15 allows remote attackers to read database data through the Store API. ProductQueryFilters sanitizes attacker-controlled taxonomy names without SQL escaping before interpolating them into an IN clause. No authentication or user interaction is required; crafted collection-data requests can disclose administrative account IDs, email addresses, and password hashes.
