Doc Text:
A flaw was found in Apache Tomcat. When the server is configured to enforce FIPS (Federal Information Processing Standards) mode, a failure during FIPS activation causes Tomcat to log an error and continue running with standard non-FIPS cryptographic providers instead of terminating securely. This allows the application to process secure connections using unapproved or weaker cryptography, which may violate compliance mandates and weaken expected cryptographic protections.

Description OSIDB Bzimport 2026-10-20 13:52:57 UTC
Not Failing Securely ('Failing Open') vulnerability in Apache Tomcat. If the OpenSSLLifecycleListener is configured to use FIPS mode but FIPS activation fails, Tomcat logs and error but continues to use JSSE in non-FIPS mode with the provided configuration.



This issue affects Apache Tomcat: from 11.0.0-M14 through 11.0.26, from 10.1.22 through 10.1.60, from 9.0.92 through 9.0.122.



Users are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fix the issue.
