AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Global installation automatically replaces the system-wide `codex` command with this package's launcher. It can delete an existing launcher and directs later Codex use to @codexed binaries.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm global installation

Impact

Hijacks a broad AI-agent CLI control surface and causes future `codex` invocations to execute package-selected binaries.

Mechanism

postinstall overwrites global Codex launchers

Policy narrative

During global installation, the postinstall hook derives the npm prefix (defaulting to /usr/local), removes an existing `codex` launcher, and replaces it with a link or Windows scripts invoking this package. Subsequent user execution of `codex` resolves and spawns a binary from @codexed platform packages. This is an unconsented install-time takeover of the globally named Codex agent command.

Rationale

Source inspection confirms a postinstall hook that overwrites a pre-existing global Codex launcher, rather than relying on package-manager-owned bin linking. That creates a concrete broad AI-agent control-surface hijack.

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 95.0% confidence with low false-positive risk.

Evidence for policy risk

postinstall executes automatically on installation.
On global installs it selects npm prefix or defaults to /usr/local.
It deletes the existing global `codex` launcher before replacing it with a symlink to this package.
On Windows it overwrites `codex.cmd` and `codex.ps1` to invoke this package.
The replacement command launches a platform binary from @codexed packages.

Evidence against

Inspected JavaScript contains no credential harvesting, network requests, or exfiltration logic.
The binary is started only when the user invokes `codex`.
