CVE-2026-44877Network attack vector

Cryptographic secret disclosure via undisclosed mechanism

Published Jul 7, 2026 · Updated Jul 7, 2026

Information disclosure in HPE Networking Instant On switches 3.0.0 through 3.3.3 allows attackers to obtain cryptographic secrets. The bulletin does not identify the affected component or explain how the switch exposes secret material to network input. The affected 1830, 1930, and 1960 models expose confidentiality only; HPE calls the path unauthenticated, but its CVSS vector requires low privileges.
