    Codex has sandbox bypass due to bug in path configuration logic

    CVE-2025-59532 · GHSA-w5fx-fh39-j5rw

    Affected
    • npm @openai/codex >= 0.2.0, <= 0.38.0
    Fixed in
    0.39.0· Vendor fix available
    Issue
    Due to a bug in the sandbox configuration logic, Codex CLI could treat a model-generated cwd as the sandbox’s writable root, including paths outside of the folder where the user started their session. This logic bypassed the intended workspace boundary and enables arbitrary file writes and command execution where the Codex process has permissions - this did not impact the network-disabled sandbox restriction. Remediation We released a patch in Codex CLI 0.39.0 that canonicalizes and validates that the boundary used for sandbox policy is based on where the user started the session, and not the one generated by the model. Users running 0.38.0 or earlier should update immediately via their package manager or by reinstalling the latest Codex CLI to ensure sandbox boundaries are enforced. If using the Codex IDE extension, users should immediately update to 0.4.12 for a fix of the sandbox issue. Thank you to Tzanko Matev (Codetracer) for reporting the issue!

    Recommended action: Upgrade to 0.39.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
