"Unintentional Exposure of API Token in a Public Repository: Security Implications and Recommendations"

[moustafa320]

URL: https://api.replicate.com/v1/predictions

1. Introduction:

This report outlines a potential security vulnerability discovered in the API service provided by Replicate. While performing routine analysis, I came across a token that could have significant implications if mishandled. Although I couldn't retrieve sensitive information through the token, I felt it was important to report its existence due to the security risk it may present.

2. Vulnerability Summary:

The discovered vulnerability involves the usage of an API token found in a public repository. The token allowed for API requests, but the responses returned were empty. This raises concerns about token exposure and potential misuse, especially in the case of unauthorized access to API endpoints. Although no sensitive data was retrieved during my tests, the exposure of the token could lead to a significant security risk.

The token was found at the following public repository:

[Token Source](https://github.com/GloryDream413/Bot_MARS/blob/0cf4318a634a767266e6c752acf789b927753400/1.txt#L50)

3. Technical Details:

The vulnerability was tested using the following command to perform a GET request on Replicate's API:

bash

curl -X GET "https://api.replicate.com/v1/predictions" \ -H "Authorization: Token 51cb9f81de883a011305cf4da2346c7c99545d31"

The response received from this API call was as follows:

json

{"next":null,"previous":null,"results":[]}

Although the token did not return any valuable data, the ability to execute requests using it remains a security risk.

4. Steps to Reproduce:

To reproduce the issue, follow these steps:

Access the publicly available token from the source link mentioned.
Perform an API request to Replicate's /v1/predictions endpoint using the token via the command shown above.
Observe that the request succeeds but returns an empty response without any error regarding the token's validity or expiration.

5. Security Impact:

The exposure of this token in a public repository poses a potential security risk. Although no sensitive data was returned, unauthorized users could exploit this token to make additional API calls or attempt to gain further access to the system. Misuse of such tokens could lead to data leaks or other exploitations if further weaknesses are discovered.

6. Recommendations:

It is recommended that:

Tokens used in the API are regularly rotated and invalidated when exposed.
Public repositories are scanned for exposed credentials to prevent such issues.
Additional logging and alerts are set up to detect the misuse of expired or exposed tokens.
Ensure that API endpoints return proper error messages if a token is invalid or expired, instead of merely returning empty results.

7. Conclusion:

While I was unable to extract any sensitive information using the exposed token, its existence in a public repository signals a potential risk for exploitation. Immediate action should be taken to investigate the origin and scope of the token's usage and exposure.
