CVE-2026-59084
Description
A flaw was found in Apache Tomcat. Insufficient technical documentation regarding the secure configuration of the EncryptInterceptor component may lead to deployments with insecure settings. This vulnerability could allow an attacker to exploit misconfigurations that arise from unclear guidance, potentially compromising the confidentiality or integrity of data processed by the affected system.
Statement
This Low impact vulnerability in Apache Tomcat arises from insufficient documentation for the EncryptInterceptor. Without clear guidance on secure configuration, administrators might inadvertently deploy the interceptor in a way that weakens security, rather than a direct code flaw. This issue affects Red Hat products utilizing Apache Tomcat, including Red Hat Enterprise Linux and Red Hat JBoss Web Server.
Mitigation
To mitigate this issue, ensure that the EncryptInterceptor in Apache Tomcat is configured according to secure best practices. Review existing configurations of EncryptInterceptor to verify that all security requirements are met and that no insecure settings are in place. If the EncryptInterceptor is not actively used, no specific action is required.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
