What is CVE-2026-55276?

A vulnerability in Apache Tomcat allows for improper control flow implementations that result in special roles and empty authorization constraints being excluded from logs generated from the effective web.xml file. This oversight could potentially lead to security risks, as essential authorization information may not be accurately captured or monitored.
