CVE-2026-59084 is a low-severity vulnerability in Apache Tomcat caused by insufficient technical documentation for securely configuring the EncryptInterceptor. The issue does not describe an implementation flaw in the interceptor itself; rather, the security weakness arises because the requirements necessary to deploy EncryptInterceptor securely were not clearly documented. As a result, administrators could configure the feature in an insecure manner without being adequately informed of the required safeguards. The issue affects Apache Tomcat 11.0.0-M1 through 11.0.23, 10.1.0-M1 through 10.1.56, 9.0.13 through 9.0.119, 8.5.38 through 8.5.100, and 7.0.100 through 7.0.109. Other end-of-support versions may also be affected.
