Security Advisory: Newly Disclosed PHP Vulnerabilities
 

We are aware of the recently disclosed security vulnerabilities affecting PHP and have proactively assessed our environment to determine any potential exposure.
 

Following a review of our systems, applications, and infrastructure, we have confirmed that PHP is not used within our environment. As a result, our systems are not impacted by these vulnerabilities, and no remediation actions are required at this time.
 

We remain committed to maintaining a strong security posture and will continue to monitor emerging threats and vulnerabilities to ensure the ongoing security of our systems and customer data.
