Fix: authentication required to GET avatars' default image #300
Conversation
Fixes #299 Remove authentication requirement for getting default avatar image. * **AvatarsController**: - Remove `@Guard('query-default', 'avatar')` decorator from `getDefaultAvatar` method. - Add `@NoAuth()` decorator to `getDefaultAvatar` method. - Remove `@Headers('Authorization') @authtoken() auth: string` parameter from `getDefaultAvatar` method. * **Tests**: - Remove authentication requirement for the test case that gets the default avatar image. - Update the test case to reflect the change in the `getDefaultAvatar` method. - Add a test case to validate that authentication is not required for `getAvatar`. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/SageSeekerSociety/cheese-backend/issues/299?shareId=XXXX-XXXX-XXXX-XXXX).

1-155: Consider security implications of removing authentication.The changes to
getDefaultAvatarandgetAvatarmethods align with the PR objectives of making these endpoints accessible without authentication. However, it's crucial to ensure that these changes don't inadvertently expose sensitive information or create security vulnerabilities.Recommendations:
- Conduct a thorough security review to confirm that the avatars accessible through these endpoints don't contain any sensitive or personally identifiable information.
- Implement rate limiting on these endpoints to prevent potential abuse or DoS attacks.
- Ensure that the
idparameter in thegetAvatarmethod is properly validated to prevent unauthorized access to non-public avatars.Consider implementing the following security measures:
- Add rate limiting middleware:
import { Injectable, NestMiddleware } from '@nestjs/common'; import { Request, Response, NextFunction } from 'express'; import * as rateLimit from 'express-rate-limit'; @Injectable() export class RateLimitMiddleware implements NestMiddleware { private limiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100 // limit each IP to 100 requests per windowMs }); use(req: Request, res: Response, next: NextFunction) { this.limiter(req, res, next); } }
- Enhance input validation for the
idparameter:import { ParseIntPipe, BadRequestException } from '@nestjs/common'; // In the getAvatar method @Param('id', new ParseIntPipe({ errorHttpStatusCode: BadRequestException })) id: number
- Implement logging for these public endpoints to monitor usage and detect potential abuse.

112-125: LGTM! Consider adding an explicit check for unauthenticated access.The new test case successfully verifies that an avatar can be retrieved without authentication, which aligns with the PR objectives. It checks for the correct status code and expected headers, which is great.
To make the test even more robust, consider adding an explicit check to ensure that the request succeeds even when an invalid authorization token is provided. This would more definitively prove that authentication is not required. For example:
const respond = await request(app.getHttpServer()) .get(`/avatars/${avatarId}`) .set('Authorization', 'Bearer invalid_token') .send() .responseType('blob');This addition would further strengthen the test case and leave no doubt about the removal of the authentication requirement.

127-137: Enhance test coverage for default avatar retrievalWhile this test case correctly doesn't include an authentication header, it doesn't explicitly verify that authentication is no longer required for the default avatar. This aligns with the PR objectives, but the test could be more robust.
Consider adding an additional assertion or a separate test case to explicitly verify that the default avatar can be retrieved even with an invalid authentication token. This would more clearly demonstrate that the authentication requirement has been removed. For example:
it('should get default avatar with invalid token', async () => { const respond = await request(app.getHttpServer()) .get('/avatars/default') .set('Authorization', 'Bearer invalid_token') .send(); expect(respond.status).toBe(200); // ... (other assertions) });This addition would provide stronger evidence that the PR objective of removing authentication for the default avatar has been met.

84-89: Approved, but clarification needed on intent.The removal of the
authparameter from thegetAvatarmethod is consistent with the existing@NoAuth()decorator. However, the PR objectives didn't explicitly mention changes to this method, which retrieves a specific avatar by ID, not the default avatar.Could you please clarify the intent behind modifying this method? Was it to maintain consistency with the
getDefaultAvatarmethod, or are there additional considerations?Let's verify that this change doesn't introduce any unintended side effects:
Verification successful
Auth Parameter Removal Verified
The removal of the
authparameter from thegetAvatarmethod does not introduce any unintended side effects, as there are no remaining usages ofauthin theAvatarsControlleror client-side code.Scripts executed
The following scripts were executed for the analysis:

50-55: LGTM! Changes align with PR objectives.The modifications to the
getDefaultAvatarmethod successfully remove the authentication requirement for retrieving the default avatar image. The addition of the@NoAuth()decorator and the removal of theauthparameter are consistent with this goal.To ensure consistency across the codebase, let's verify that no other parts of the application still expect authentication for this endpoint:

68-74: Clarify the status of the commented-out test caseThere's a commented-out test case that checks for an AuthenticationRequiredError when no token is provided. Given the changes in authentication requirements for avatar retrieval, it's unclear whether this test case should be removed, updated, or left as is.
Could you please clarify the intended behavior for this test case? If it's no longer relevant due to the changes in authentication requirements, it might be better to remove it entirely. If it's still relevant for certain scenarios, consider updating it to reflect the new authentication rules.
To help verify the current behavior, you can run the following script:
This will help determine if there are any remaining cases where AuthenticationRequiredError is thrown for avatar-related operations, which can guide the decision on whether to keep, update, or remove this test case.
