CVE-2026-81320 Published on September 15, 2026
Hawtio-operator: hawtio-operator: tls private key written to operator log at debug level
A flaw was found in hawtio-operator. When a custom Route TLS secret is configured and the operator runs at debug log level 1 or higher, the entire Route object including the TLS private key in PEM format is serialized to JSON and written to the operator's standard output. Operator logs are typically forwarded to centralized logging systems and readable by anyone with pods/log access in the openshift-operators namespace. Debug level 1 is a low threshold commonly enabled during troubleshooting.
