Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Cross-Site Request Forgery (CSRF) vulnerability in the PI Websolution shipping plugin for WooCommerce allows attackers to potentially force authenticated administrators to perform unintended shipping configuration changes by tricking them into visiting malicious pages while logged in.

MitigationUpdate the plugin to a version greater than 1.6.4.4 which should include proper CSRF token validation; alternatively, implement anti-CSRF tokens on all state-changing operations within the plugin.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
