BeyondTrust Phantom Labs finds critical OpenAI Codex vulnerability
Researchers at BeyondTrust Phantom Labs have identified a critical command injection vulnerability in OpenAI’s Codex cloud environment that exposed GitHub OAuth tokens directly from the agent’s execution environment. The vulnerability stemmed from improper input sanitisation in how Codex processed GitHub branch names during task execution. By injecting arbitrary commands through the GitHub branch name parameter, an attacker could execute malicio…
What if a simple branch name in your repository becomes the digital general key for your entire GitHub organization? Security researchers have discovered a method by which attackers could trick OpenAI Codex and steal highly sensitive OAuth tokens via invisible Unicode commands. The risk does not only concern individual developers, but the entire toolchain. We'll show you why your AI agents might reveal more than you like in the background. The s…
