CVE-2026-5846

Estado: AplazadaAlta (7.6)—

The affected Watchfire Controller Software contains self-signed hard-coded RSA private keys and corresponding X.509 certificates used for authenticating and encrypting HTTPS/TLS connections to the controller's built-in web management interface. These keys are embedded in plaintext within the application patch binaries in the firmware directly from Watchfire's Remote Support filestore.
