CyberRota Analysis
AI-GeneratedCloudreve versions prior to 4.17.0 are vulnerable to an information disclosure flaw that allows authenticated users to enumerate email addresses and profile metadata of inactive or banned accounts through the API. This exposure arises from the lack of a StatusActive filter in the user search functionality, which could lead to unauthorized access to sensitive user information. Organizations using affected versions should prioritize upgrading to 4.17.0 to mitigate this risk.

Original NVD Description
Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, GET /api/v4/user/search calls SearchActive without adding a StatusActive predicate and serializes matches at RedactLevelUser, allowing any logged-in user to enumerate email addresses and profile metadata for inactive or banned accounts. The service calls userClient.SearchActive, but despite its name that method filters only by email/nickname keyword and never adds a StatusActive predicate — while the sibling lookups GetActiveByID and GetActiveByDavAccount, defined a few lines above it, do. Search hits are serialized at RedactLevelUser, which includes the email address. This issue is fixed in version 4.17.0.
