CVE-2026-103119
CVE-2026-103119 · Apache Tomcat: AJP response mix-up
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Buffer under-read vulnerability in Apache Tomcat meant that a large non-blocking write could result in the response body being split between the current request and the next request received on that connection leading most likely to failure of the second request and possibly leakage of data from the first response to the second. This issue affects Apache Tomcat: from 11.0.0-M25 through 11.0.26. Users are recommended to upgrade to version 11.0.27, which fixes the issue.
