CoCart: Cross-Site Request Forgery enables administrator account creation
Summary
CoCart, a WordPress plugin that provides a REST API for WooCommerce carts, before version 4.9.7 does not limit its REST API authentication filter to its own endpoints. This disables WordPress core's REST nonce protection for all routes. An attacker can use a cross-site request forgery attack to create a new administrator account while a logged-in administrator visits a malicious page.
Affected
- CoCart versions 4.9.0 to before 4.9.7 (lower bound per third-party sources; versions before 4.9.0 unknown)
- WordPress/WooCommerce sites with the plugin installed
Fixed in
- Update to CoCart 4.9.7 or later
Workaround
- No official workaround known. The vendor fix is the update to 4.9.7.
- Until patched, deactivate the plugin if the headless cart is not used (suggestion, not a vendor recommendation).
- Until patched, administrators should avoid browsing untrusted websites while logged into the WordPress admin area.
Exploitation
- No evidence of exploitation in the wild found.
- CISA KEV status: not listed according to a third-party aggregator; not verified directly against the CISA catalogue.
- EPSS score 0.11% according to a third-party aggregator.
- Public proof-of-concept status unverified.
Our recommendation
- Check whether the CoCart plugin is installed on any WordPress/WooCommerce site and which version it runs.
- Update to CoCart 4.9.7 or later.
- Review administrator user lists for unexpected administrator accounts, especially on sites that were unpatched.
- Monitor the WPScan, NVD and CISA KEV pages for changes in exploitation status.

Original description (NVD)
The CoCart WordPress plugin before 4.9.7 does not scope its REST API authentication filter to its own endpoints, which disables WordPress core's REST nonce protection for every route, allowing an attacker to perform a cross-site request forgery attack that creates a new administrator account using a logged-in administrator's session.
