Summary
Pydio Cells 5.0.0 through 5.0.2 exposes share-link details to any authenticated user. The REST handler for GET /a/share/link/{Uuid} lacks authorization checks, and the workspace UUID is not secret as it is embedded in the public page. An attacker with a standard user role can obtain the link hash, URL, owner ID, hidden login, permissions, download limits, target users, expiry, and password-required flag.
Risk Assessment
The risk involves unauthorized access to sensitive information about shared resources, potentially leading to data leakage and confidentiality breaches.
Recommendation
Immediately upgrade Pydio Cells to a patched version and enforce access controls at the API level.

Original NVD description (English source)
Pydio Cells 5.0.0 through 5.0.2 returns share-link details to any authenticated user. The REST handler for GET /a/share/link/{Uuid} in idm/share/rest/handler.go reads the workspace UUID from the path, calls LinkById, and writes the result with no authorization step, whereas the sibling handler for GET /a/share/cell/{Uuid} loads the workspace and requires MatchPolicies with ResourcePolicyAction_READ, returning a not-found error so that existence is not disclosed. Nothing compensates further down: GetLinkWorkspace reaches GetOrCreateWorkspace, which issues SearchWorkspace with a query carrying no ResourcePolicyQuery, and PrepareResourcePolicyQuery returns the query unmodified when that field is nil, so the workspace service applies no policy filter. The workspace UUID is not secret, because the unauthenticated public page served for a share link embeds it as START_REPOSITORY. Any account holding a standard user role can therefore submit the UUID and receive the link hash and URL, the owner's user identifier, the hidden share user login, the permission set, the download limit and count, the target users, the expiry, and the password-required flag, while a direct read of the shared node from the same account is refused.
