When responding to new h2c connection requests, Apache Tomcat versions 9.0.0.M1 to 9.0.41 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A’s request (CVE-2021-25122). The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 9.0.0.M1 to 9.0.41 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494 (CVE-2021-25329).
