Codex Security plugin returns as an open-source codebase threat-modeling tool
The post reintroduces the Codex Security plugin and says it can be pointed at a codebase or diff to:
- build a threat model
- map attack paths
- validate findings
- generate and test fixes
- export results to SARIF, GitHub, Jira, or Linear
It is also described as open source on GitHub, which makes it more than a demo: it is positioned as a practical security workflow tool for developers and security teams.
