GHSA-qxf4-chvg-4r8r
Potential HTTP request smuggling in Apache Tomcat
Quick fix
GHSA-qxf4-chvg-4r8r — org.apache.tomcat.embed:tomcat-embed-core: upgrade to the fixed version with the command below.
# pom.xml: bump <version>7.0.100</version> for org.apache.tomcat.embed:tomcat-embed-coreDetails
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
