NEXO Privilege Gate v0.4.0 is an open-source least-privilege gateway for AI agents. It now enforces structured filesystem actions inside a local sandbox, blocks path escapes and sensitive-file aliases, requires human approval for destructive actions, quarantines deletions, and records a tamper-evident audit trail. GPT-6 Astra also found and helped fix a real path-alias authorization bypass before release.

Could you build this?
No Developing a secure privilege gateway that safely sandboxes untrusted agent actions, prevents path traversal/symlink escapes, and maintains tamper-evident audit logs requires specialized systems and OS-level security engineering.
What it would actually take: This requires implementing low-level OS isolation primitives (Linux namespaces, cgroups, seccomp filters, or platforms like gVisor/Wasmtime) to enforce strict sandbox boundaries. Preventing race conditions (TOCTOU attacks), canonicalizing path traversals reliably across arbitrary file systems, and generating cryptographically signed append-only audit logs (e.g., using Merkle trees like Trillian) necessitates systems security engineering expertise.
