π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

In `@apps/api/src/http/server.ts`:
- Around line 69-70: The CORS registration currently calls await
app.register(cors) which defaults to allowing all origins; update the
registration to pass an explicit options object to cors (the call that registers
`@fastify/cors`) specifying allowed origins (origin as a string, array of strings,
or validator function) and allowedMethods (e.g., GET, POST, PUT, DELETE,
OPTIONS) and any other strict settings like credentials and allowedHeaders;
locate the cors registration in server.ts (the await app.register(cors) call)
and replace it with await app.register(cors, { origin: /* allowed origins */,
methods: /* allowed methods */, credentials: /* true/false */, allowedHeaders:
/* headers */ }) so the server no longer permits all origins by default.

π Web query:
For @fastify/corsv8.x, what is the default value of theorigin option when omitted, and does it allow all origins (*)?
π‘ Result:
In @fastify/cors v8.x, the default value for the origin option is '' [1][2]. Setting the option to '' allows any origin [1][3].

Closing as a duplicate during org-wide PR backlog cleanup. Keeping #27 as the canonical PR for this same issue: π‘οΈ Sentinel: [HIGH] Add security headers and CORS protection |
1 participant
π¨ Severity: MEDIUM
π‘ Vulnerability: The Fastify API lacks basic security headers to protect against common web vulnerabilities like XSS, Clickjacking, and improper MIME type sniffing, and explicit Cross-Origin Resource Sharing (CORS) configurations.
π― Impact: Without
helmet, the API relies on default fastify HTTP headers which do not adhere to best security practices and leave standard attack vectors open.π§ Fix: Add
@fastify/corsand@fastify/helmetto the main Fastify server registration, with basic secure defaults.β Verification: Ran unit tests to verify proper plugin registration flow and code linting/formatting pass.
