Codex Security plugin returns as an open-source codebase scanner with fix generation
reach_vb · x · 2026-07-23
Codex Security has been reintroduced as an open-source plugin that can point at a codebase or diff, build a threat model, map attack paths, validate findings, generate and test fixes, and export results to SARIF, GitHub, Jira, or Linear.
The screenshot shows a dedicated scan workflow inside the Codex Security UI, including codebase selection, deep-scan options, threat-model scoping, and a one-click start flow. It’s aimed at turning security review into an agent-driven coding workflow rather than a manual audit checklist.
