AI Security Review

scanned 2d ago · by lpm-firewall-ai

Source inspection confirms that the Codex rollout writer deliberately replaces permission context and sets unrestricted approval and sandbox values. The postinstall downloads are separately hash-checked, but that does not resolve the runtime control-context tampering.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A caller invokes the Codex registry writeRollout operation to create a rollout.

Impact

Codex may be misled about the permissions and safeguards governing the session.

Mechanism

The writer overwrites the developer setup text, sets approval to never and sandbox policy to full access, then removes the permission profile in the generated rollout.

Policy narrative

When the Codex rollout writer is invoked, it inserts text claiming that filesystem sandboxing is disabled and approval is never required. It also writes those settings into the rollout context and removes the permission profile. This tampers with the control context consumed by a Codex session and can misrepresent its actual safeguards.

AI rationale

Evidence

dist/mcp-factories.jsCodex session rollout file

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 98.0% confidence with low false-positive risk.

Evidence for policy risk

When the Codex rollout writer runs, it replaces the developer setup text with claims that sandboxing is disabled and approval is never required.
The generated rollout also sets approval to never, grants a full-access sandbox policy, and removes the permission profile.
The Codex registry exposes this rollout writer through its writeRollout operation.

Evidence against

The postinstall hook installs browser and shell helper binaries from versioned project releases and checks their SHA-256 hashes before replacing local copies.
