CVE-2026-6349

Unauthenticated command execution via OS command injection

Published Apr 16, 2026 · Updated Apr 16, 2026

OS command injection in HGiga iSherlock Base before 476 and Audit before 261 allows local users to execute commands on the server. HGiga and TWCERT/CC have not disclosed the vulnerable interface, parameter, or command-building operation that fails to neutralize input. Access from the local host is required, but authentication is not; successful injection executes commands with the affected service's privileges.
