CVE-2026-87888 Details
Description
The YayPricing WordPress plugin before 3.5.7 does not perform an authorization check on a REST route that saves its pricing rules, allowing users with the subscriber role and above to store JavaScript that executes in the browser of an administrator who opens the YayPricing WordPress plugin before 3.5.7's settings page.
A stored cross-site scripting vulnerability has been identified in the YayPricing WordPress plugin, affecting versions prior to 3.5.7. The issue arises because the plugin does not implement proper authorization checks on a REST route used to save pricing rules. This oversight allows users with subscriber roles and above to inject JavaScript that executes in the browser of an administrator who accesses the plugin's settings page.
Users are advised to update the YayPricing WordPress plugin to version 3.5.7 or later.
