OpenAI announced Codex Security on March 6, 2026 as a research preview focused on vulnerability discovery, validation, and patch proposals with lower triage noise. For WordPress plugin and Drupal module teams using coding agents, the big change is not "replace SAST." It is adding a context-aware security reviewer between implementation and merge.
