CVE-2026-77474Public exploitHinoki check available

Guard bypass via exponential-time substitution scanning

Published Oct 16, 2026 · Updated Oct 16, 2026

Algorithmic DoS in Destructive Command Guard before 0.6.6 allows attackers to bypass command blocking via crafted shell input. In src/packs/mod.rs, substitution scanners reached through split_command_segments repeatedly rescan command suffixes after nested scans report unterminated input, causing exponential work. Exploitation requires attacker-controlled commands to reach an agent hook that fails open on timeout, allowing destructive commands to execute with the agent's existing permissions.
