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.

Pull request overview
This PR aims to mitigate a potential DoS vector by enforcing a maximum password length (1024 chars) at the Zod validation layer before passwords reach expensive cryptographic operations (bcrypt hashing/compare) in the web app and shared auth schemas.
Changes:
- Add
.max(1024)to password validation for password reset and admin login API routes. - Add
.max(1024)to sharedLoginRequestSchema/RegisterRequestSchema. - Document the vulnerability and prevention guidance in
.jules/sentinel.md.

LoginRequestSchema/RegisterRequestSchemahave existing Vitest coverage, but the newly added.max(1024)constraint isnβt tested. Add a test case inpackages/shared/src/schemas/auth.test.tsthat asserts passwords longer than 1024 characters fail parsing (and optionally that exactly 1024 succeeds) to prevent regressions.
export const LoginRequestSchema = z.object({
email: z.string().email(),
password: z.string().min(8).max(1024),
})
export const RegisterRequestSchema = z.object({
email: z.string().email(),
password: z.string().min(8).max(1024),
name: z.string().min(1),

packages/shared/src/schemas/auth.ts:5
- Password max length is now enforced in the shared schemas, but the NextAuth Credentials authorize() flow still accepts an unbounded
credentials.passwordand passes it tologinUser()/bcrypt.compare(). To fully mitigate the intended DoS vector, add the same length cap inpackages/web/src/auth.ts(or defensively insideloginUser()) before calling bcrypt.
password: z.string().min(8).max(1024),
.jules/sentinel.md:22
- The learning note states that bcrypt runtime grows exponentially with input length. Bcrypt's cost is primarily driven by the work factor, and many implementations only use the first ~72 bytes of the password. The recommendation to cap password length is still reasonable, but the explanation should be corrected to avoid propagating incorrect security guidance.
**Learning:** Bcrypt computation time grows exponentially with the length of the input string. Without a strict maximum length limit (e.g., `.max(1024)` in Zod), an attacker can cause CPU exhaustion (Denial of Service) by submitting excessively long passwords, blocking the event loop and bringing down the server.
