CVE-2025-13457Network attack vectorHinoki check available

Payment-token disclosure via unchecked object key

Published Jan 10, 2026 · Updated Jan 10, 2026

IDOR in affected Square for WooCommerce releases through 5.1.1 allows remote attackers to read stored Square credit-card-on-file tokens. The get_token_by_id function uses an attacker-controlled key to retrieve a ccof value without validating authorization for the referenced token. No account or user interaction is required; disclosure is limited to stored Square payment tokens, which can enable fraudulent site charges.
