Published Feb 17, 2026CWE-20EPSS 0.55%

Overview

CVE-2026-24733 is a low-severity vulnerability. It was published on February 17, 2026 and has a CVSS 3.1 base score of 3.7 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.7, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
