Title
Coolify: Cross-team application domain enumeration via domains_by_server endpoint
Summary
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, `GET /api/v1/servers/{server_uuid}/domains?uuid={app_uuid}` bypasses team scoping when the optional uuid query parameter is provided. Any authenticated API user can enumerate domain names (FQDNs) of applications belonging to other teams. This vulnerability is fixed in 4.0.0-beta.464.

CVE-2026-27943 (GCVE-0-2026-27943)

Title
OpenEMR's Eye Exam View Trusts form_id Without Verifying Patient/Encounter Ownership
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. In versions up to and including 8.0.0, the eye exam (eye_mag) view loads data by `form_id` (or equivalent) without verifying that the form belongs to the current user’s patient/encounter context. An authenticated user can access or edit any patient’s eye exam by supplying another form ID; in some flows the session’s active patient may also be switched. A fix is available on the `main` branch of the OpenEMR GitHub repository.

Title
Vaultwarden: Unauthorized Access via Partial Update API on Another User’s Cipher
Summary
Vaultwarden is an unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs. Prior to version 1.35.4, an authenticated regular user can specify another user’s cipher_id and call "PUT /api/ciphers/{id}/partial" Even though the standard retrieval API correctly denies access to that cipher, the partial update endpoint returns 200 OK and exposes cipherDetails (including name, notes, data, secureNote, etc.). This issue has been patched in version 1.35.4.

Title
Coolify: IDOR in Deployment API - Cross-Team Deployment Information Disclosure
Summary
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the `GET /api/v1/deployments/{uuid}` endpoint allows any authenticated user to access deployment details belonging to any team, bypassing team-based authorization. The $teamId is extracted from the authentication token but never used to scope the database query. This vulnerability is fixed in 4.0.0-beta.464.

Title
Coolify: Cross-team deployment information disclosure via GET /api/v1/deployments/{uuid} (IDOR)
Summary
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, `GET /api/v1/deployments/{uuid}` in DeployController.php retrieves deployment details without validating that the deployment belongs to the authenticated user's team. Any authenticated API user can read deployment records from other teams by providing a valid deployment UUID. This vulnerability is fixed in 4.0.0-beta.464.

Title
wger: IDOR in nutritional_values endpoints exposes private dietary data via direct ORM lookup
Summary
wger is a free, open-source workout and fitness manager. In versions up to and including 2.4, three `nutritional_values` action endpoints fetch objects via `Model.objects.get(pk=pk)` — a raw ORM call that bypasses the user-scoped queryset. Any authenticated user can read another user's private nutrition plan data, including caloric intake and full macro breakdown, by supplying an arbitrary PK. Commit 29876a1954fe959e4b58ef070170e81703dab60e contains a fix for the issue.

wger: IDOR via user-unscoped cache keys on routine API actions exposes workout data
Summary
wger is a free, open-source workout and fitness manager. Five routine detail action endpoints check a cache before calling `self.get_object()`. In versions up to and including 2.4, ache keys are scoped only by `pk` — no user ID is included. When a victim has previously accessed their routine via the API, an attacker can retrieve the cached response for the same PK without any ownership check. Commit e964328784e2ee2830a1991d69fadbce86ac9fbf contains a patch for the issue.

Title
wger: IDOR in RepetitionsConfig and MaxRepetitionsConfig API leak other users' workout data
Summary
wger is a free, open-source workout and fitness manager. In versions up to and including 2.4, `RepetitionsConfigViewSet` and `MaxRepetitionsConfigViewSet` return all users' repetition config data because their `get_queryset()` calls `.all()` instead of filtering by the authenticated user. Any registered user can enumerate every other user's workout structure. Commit 1fda5690b35706bb137850c8a084ec6a13317b64 contains a fix for the issue.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
