| CVE-2026-55495 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 4.3 Medium |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, the WOPI PUT_RELATIVE handler passes X-WOPI-SuggestedTarget to URI.JoinRaw as a path rather than a filename, allowing slash and dot-dot segments to escape the source file directory and create or conditionally overwrite files elsewhere in the same owner account. This issue is fixed in version 4.17.0. | ||||
| CVE-2026-55496 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 4.3 Medium |
| 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. | ||||
| CVE-2026-55497 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 6.5 Medium |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, the built-in thumbnail and avatar image decoders limit compressed file size but do not limit decoded pixel dimensions, allowing an authenticated user to submit a small PNG, JPEG, or GIF that triggers an unbounded allocation and terminates the Cloudreve process through fatal out-of-memory behavior. This issue is fixed in version 4.17.0. | ||||
| CVE-2026-55499 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 4.3 Medium |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, a single-file share event-stream subscription resolves the share root to the owner’s parent folder and subscribes to that folder topic, allowing an authenticated share recipient to receive names, paths, rename targets, event types, and hashed identifiers for unshared sibling files and folders. This issue is fixed in version 4.17.0. | ||||
| CVE-2026-55502 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 7.1 High |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, POST /api/v4/admin/policy/oauth/signin requires only Admin.Read even though GetOauthRedirectService persists caller-supplied OneDrive secret and app_id values, allowing an OAuth token without Admin.Write to modify storage policy credentials. The route is inside the admin group that requires Admin.Read, but it does not add the local Admin.Write guard used by sibling policy mutation routes. Its handler persists attacker-supplied secret and app_id values into the selected OneDrive storage policy before returning an OAuth URL. This issue is fixed in version 4.17.0. | ||||
| CVE-2026-62323 | 1 Cloudreve | 1 Cloudreve | 2026-07-31 | 6.3 Medium |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, ViewerSessionValidation uses only the session-id prefix of a WOPI access token and does not enforce the requested viewer action, allowing a malicious or compromised WOPI viewer with a view session to forge the token suffix and invoke WOPI write routes for the underlying file. This issue is fixed in version 4.17.0. | ||||
| CVE-2026-54562 | 1 Cloudreve | 1 Cloudreve | 2026-07-15 | 6.5 Medium |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.16.1, Cloudreve's remote download workflow accepts user-supplied URLs at POST /api/v4/workflow/download and passes them to the configured downloader without blocking loopback, localhost, IPv6 localhost, or redirect-to-loopback targets, allowing a non-admin user with remote download permission to fetch internal-only URLs and read the response after it is imported into the user's own files. This issue is fixed in version 4.16.1. | ||||
| CVE-2026-54563 | 1 Cloudreve | 1 Cloudreve | 2026-07-15 | 7.1 High |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.16.1, a Cloudreve WebDAV account rooted at a configured folder can send paths such as /dav/%2e%2e/outside.txt because stripPrefix in pkg/webdav/webdav.go joins the decoded request suffix to the account root with fs.URI.JoinRaw without checking containment, allowing the scoped credential to read and list files outside the configured folder and writable credentials to create, overwrite, move, or delete them. This issue is reported as fixed in version 4.16.1. | ||||
| CVE-2026-54560 | 1 Cloudreve | 1 Cloudreve | 2026-07-15 | 7.6 High |
| Cloudreve is a self-hosted file management and sharing system. From 4.12.0 until 4.16.1, Cloudreve's OAuth access tokens are issued without the OAuth client_id claim, so the JWT verifier does not load token scopes into request context and RequiredScopes treats the request like non-scoped session authentication, allowing a low-scope OAuth access token to call APIs requiring higher scopes such as file, share, workflow, user setting, WebDAV account, and potentially admin scopes. This issue is fixed in version 4.16.1. | ||||
| CVE-2026-25726 | 1 Cloudreve | 1 Cloudreve | 2026-04-14 | 8.1 High |
| Cloudreve is a self-hosted file management and sharing system. Prior to version 4.13.0, the application uses the weak pseudo-random number generator math/rand seeded with time.Now().UnixNano() to generate critical security secrets, including the secret_key, and hash_id_salt. These secrets are generated upon first startup and persisted in the database. An attacker can exploit this by obtaining the administrator's account creation time (via public API endpoints) to narrow the search window for the PRNG seed, and use known hashid to validate the seed. By brute-forcing the seed (demonstrated to take <3 hours on general consumer PC), an attacker can predict the secret_key. This allows them to forge valid JSON Web Tokens (JWTs) for any user, including administrators, leading to full account takeover and privilege escalation. This issue has been patched in version 4.13.0. | ||||
| CVE-2022-32167 | 1 Cloudreve | 1 Cloudreve | 2025-05-29 | 5.4 Medium |
| Cloudreve versions v1.0.0 through v3.5.3 are vulnerable to Stored Cross-Site Scripting (XSS), via the file upload functionality. A low privileged user will be able to share a file with an admin user, which could lead to privilege escalation. | ||||
