No. This vulnerability is in unpatched versions of Apache Tomcat.
Integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4,
when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header.
The PSC does not use these unpatched versions of Apache Tomcat, and we regularly scan our infrastructure for vulnerabilities and implement the requisite patches.
