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.\n\n## Vendor advisories\n\n- **RHSA-2026:85926** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:85926)\n- **RHSA-2026:81365** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-12 · [advisory](https://access.redhat.com/errata/RHSA-2026:81365)\n\n**tomcat: Tomcat: Cryptographic policy bypass via FIPS activation failure** — rated Low by Red Hat.
