Published: 10 January 2026
Summary
CVE-2025-13457 is a high-severity Authorization Bypass Through User-Controlled Key (CWE-639) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-13457 is an Insecure Direct Object Reference (IDOR) vulnerability, classified under CWE-639, affecting the WooCommerce Square plugin for WordPress in all versions up to and including 5.1.1. The flaw resides in the get_token_by_id function, which lacks proper validation of a user-controlled key, allowing unauthorized access to sensitive data.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges required, as indicated by its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Successful exploitation enables exposure of arbitrary Square "ccof" (credit card on file) values, which attackers can then leverage to potentially make fraudulent charges on the affected site.
Mitigation is addressed in the plugin's patch at https://plugins.trac.wordpress.org/changeset/3415850/woocommerce-square, which security practitioners should apply by updating to a version beyond 5.1.1.
