code/express-cors-wildcard
Express CORS enabled with default (wildcard) origin
What it detects
`app.use(cors())` with no options reflects/allows any origin. Configure an explicit `origin` allowlist instead of the permissive default.
How it runs
Gated on framework detection: the repo's manifests (package.json, requirements.txt, pom.xml, Gemfile, composer.json) are read to identify the stack, and the rule only runs against matching-language files when its framework is present.
