SCA: security update for org.apache.tomcat.embed:tomcat-embed-core, org.apache.tomcat:tomcat, org.apache.tomcat:tomcat-catalina (GHSA-qq5r-98hh-rxc9)

medium Tenable Cloud Security Plugin ID 437863

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Improper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the
GET method. If a security constraint was configured to allow HEAD requests to a URI but deny GET requests,
the user could bypass that constraint on GET requests by sending a (specification invalid) HEAD request
using HTTP/0.9. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through
10.1.49, from 9.0.0.M1 through 9.0.112. Older, EOL versions are also affected. Users are recommended to
upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fixes the issue.
(CVE-2026-24733)

Solution

Update the org.apache.tomcat.embed:tomcat-embed-core library and its related packages to version 10.1.50 or later.
