OpenAI Patches Codex CLI Command Injection
8.0
OpenAI on December 1, 2025 patched a command-injection flaw in its Codex CLI tool that allowed attackers to execute arbitrary commands by placing a malicious configuration file into a project repository. The issue, fixed in Codex CLI version 0.23.0, effectively turned routine 'codex' invocations into silent remote-code-execution triggers. Developers are urged to upgrade and audit repository configs to eliminate exposure.
Key Points
- 1Identifies command-injection flaw allowing arbitrary command execution via malicious Codex CLI configuration files in repositories.
- 2Highlights routine 'codex' use could silently trigger remote-code-execution, raising exploitation risk for developer machines.
- 3Advises developers to upgrade to Codex CLI 0.23.0 and audit repo configs to mitigate RCE risk.
Scoring Rationale
Significant official security patch affecting developer tooling, providing immediate mitigation but limited to Codex CLI users only.
