Description
The Cost Calculator Builder PRO WordPress plugin up to version 4.0.3 contains a critical remote code execution vulnerability due to improper sanitization in the js_to_php function. An unauthenticated attacker can exploit this by injecting malicious code into the orderDetails[*].originalValue field, which is passed unsafely to PHP eval(). The nonce intended as an authentication barrier is publicly exposed on all front-end pages, allowing attackers to bypass it. The vulnerability has a CVSS score of 9.8, indicating critical severity.
