CVE-2026-8482

Secret disclosure via NSRPC command history

Published Jul 2, 2026 · Updated Jul 2, 2026

Information disclosure in Stormshield Network Security allows remote authenticated users to read administrator secrets through an SSH session. The NSRPC client history retains secret-bearing CLI arguments and exposes them between administrator sessions rather than isolating or redacting them. Reachability requires SSH multiuser mode, prior entry of a secret-bearing command, and an account with firewall SSH access; the reported consequence is disclosure of proxy CA or TPM secrets.
