Technical Summary
Red Hat Product Security issued an advisory (RHSA-2026:36876) for Apache Tomcat included in Red Hat Enterprise Linux 9.4, addressing two vulnerabilities: CVE-2026-29146, an information disclosure vulnerability caused by a Padding Oracle attack vector in the EncryptInterceptor, and CVE-2026-34486, which allows bypassing encryption of sensitive data in the same component. These vulnerabilities could lead to unauthorized disclosure of sensitive information. The advisory provides updated Tomcat packages (version 9.0.87-2.el9_4) that fix these issues. No CVSS scores are provided in the advisory, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation of CVE-2026-29146 could result in information disclosure through a Padding Oracle vulnerability in the EncryptInterceptor, potentially exposing sensitive data. CVE-2026-34486 allows bypassing encryption of sensitive data, which could lead to exposure of protected information. Both vulnerabilities impact confidentiality of data processed by the affected Tomcat component.
Mitigation Recommendations
Red Hat has released updated Tomcat packages (version 9.0.87-2.el9_4) for Red Hat Enterprise Linux 9.4 that address these vulnerabilities.
