Target Apache Tomcat 10.1.42 is NOT AFFECTED by CVE-2020-13935. The vulnerability required validation of WebSocket frame payload length when the MSB of a 64-bit length field is set. The fix (adding validation that payloadLength >= 0 to reject negative values caused by MSB=1) was committed by upstream Apache in commit 1c1c77b0ef on June 29, 2020, and shipped in Tomcat 10.0.0-M7. This predates the target's 10.1.42 release, so the vulnerable code pattern has never been present in this version.
