CVE-2024-33552Known exploitationNetwork attack vector

Unauthenticated account takeover via unverified login email

Published May 17, 2024 · Updated Apr 28, 2026

Improper privilege management in 8theme XStore Core 5.3.8 and earlier allows remote attackers to take over any WordPress account. The process_callback third-party login handler decodes attacker-supplied opauth data, trusts its email field, and resolves that address to a user. It then issues a WooCommerce authentication cookie for the resolved account without verifying the identity provider, so no account or interaction is required.
