Red Hat Certificate System 10: improper certificate validation
Medium6.5CVE-2026-78323 · Published Aug 24, 2026 · updated Aug 28, 2026
A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.
