Codex may be misled about the permissions and safeguards governing the session. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.22.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. 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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-20T18:29:28.901Z - **Finished:** 2026-10-20T18:30:44.954Z - **Download time:** 1526 ms - **Static scan time:** 18150 ms - **AI review time:** 56376 ms - **Total time:** 76053 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The Codex rollout writer creates session data with fabricated permission context and weakened approval and sandbox settings. This can cause a Codex session to treat restricted work as unrestricted. - **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. - **Evidence paths:** dist/mcp-factories.js - **Review source:** ai\_review - **Reviewed:** 2026-10-20T18:30:44.954Z ### AI review details - **Review stage:** source\_first\_review - **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. - **Attack 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. - **Rationale:** 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. - **Files touched:** dist/mcp-factories.js, Codex session rollout file ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **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. ## Affected versions and remediation This report applies to negotium@0.22.4. - Avoid installing negotium@0.22.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
