CVE-2026-97863Network attack vectorHinoki check available

Command execution via unescaped ACL export values

Published Sep 25, 2026 · Updated Sep 25, 2026

Command injection in MISP modules 3.0.10 and earlier allows remote authenticated users to embed shell commands in exported ACL scripts. The Cisco fireSIGHT ACL export handler formats configuration, IP, URL, and event-comment values into single-quoted shell assignments without escaping apostrophes. Exploitation requires event-submission access and execution of the generated script, which runs injected commands with the analyst's privileges.
