Impact
The Yoco Payments WordPress plugin contains a path traversal flaw (CWE-22) in how it processes the file parameter. An attacker who can send a request to the plugin can craft a file name that points to any file on the server and cause the plugin to read and return its contents. This does not require any user authentication, so anyone on the public internet could potentially read configuration files, credentials, or other data that should remain confidential.
Affected Systems
All installations of the Yoco Payments plugin up to and including version 3.9.0 are affected. The plugin is distributed via the WordPress plugin repository and is used on sites that accept payments through WordPress.
Risk and Exploitability
The CVSS score of 7.5 places this vulnerability in the high‑risk category. An EPSS score of 2% indicates a low probability that attackers will target this flaw. Because the attack does not require authentication, the scope is limited to file contents of the web server, but the exposed data may be enough to facilitate additional attacks. The flaw is not listed in the CISA KEV catalog.
