CVE-2026-82369 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. Insufficient input sanitization of shell metacharacters in the Brocade SANnav CLI scripting component permits authenticated users to break out of restricted execution contexts on managed switches. An attacker with command execution permissions can leverage this flaw to run unauthorized shell commands across target fabric switches, bypassing command allow-lists and obtaining full administrative switch access. EPSS estimates a 0.51% chance of exploitation in the next 30 days.
