CVE-2026-24733

CWE-20Published: February 17, 2026· Updated: Feb 18, 2026

EPSS:0.04%probability of exploitation in 30 daysPercentile:11.0th

Official 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.
