CVE-2026-55496
CVE-2026-55496 updated by NVD
Summary
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.
