Find CVE-2026-22732 (Spring Security header suppression)

Recipe IDio.moderne.recipe.cve202622732.FindSpringSecurityHeaderSuppressionArtifactio.moderne.recipe:rewrite-cve-2026-22732

Detects code susceptible to CVE-2026-22732, where setting Content-Length via HttpServletResponse.setHeader / setIntHeader / addIntHeader (or the WebFlux equivalents) bypasses Spring Security's OnCommittedResponseWrapper, letting the container commit the response before the lazy header-writing filter runs and silently dropping security headers (X-Frame-Options, X-Content-Type-Options, Cache-Control, etc.). Also emits one data-table row per project recording the resolved Spring Security version.
