CVE, Research URL: CVE-2026-2506
Home page URL: Security reports for EM Cost Calculator
Application: EM Cost Calculator
Published on: Feb 26, 2026
Research Description: The EM Cost Calculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.3.1. This is due to the plugin storing attacker-controlled 'customer_name' data and rendering it in the admin customer list without output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the EMCC Customers page.
Affected versions: max 2.3.1.
Status: vulnerable
