BIT-tomcat-2020-13943 PUBLISHED CVSS 4.300000190734863 MEDIUM

Record from OSV · Published March 6, 2024

If an HTTP/2 client connecting to Apache Tomcat 9.0.0 through 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.
