CVE-2026-85486

Authenticated code execution via premature form evaluation

Published Oct 8, 2026 · Updated Oct 8, 2026

Eval injection in Brocade ASCG before 3.5.0 allows remote authenticated users to execute server code via configuration forms. The configuration-form processor dynamically evaluates submitted text before validating it, allowing crafted input to run as code. Exploitation requires basic application access and adjacent-network reachability, and grants control of the application.
