A vulnerability has been found in Weaviate Verba up to 2.1.3. Affected by this vulnerability is the function getenvironment of the file goldenverba/components/util.py of the component generatestream Endpoint. The manipulation leads to information disclosure. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Weaviate before 1.38.0 does not verify that a principal performing an RBAC role assignment holds the permissions granted by the assigned role. The assignRoleToUser and assignRoleToGroup handlers (POST /authz/users/{id}/assign and /authz/groups/{id}/assign) authorize only that the caller may assign roles to the target user or group, not the permissions contained in the assigned roles, unlike role creation which enforces that a user can only create roles with permissions less than or equal to its own. A user holding only the delegated assignandrevokeusers or assignandrevokegroups permission can assign the built-in admin role, or any high-privilege custom role, to itself or others, escalating to full administrative control of the database.

An issue was discovered in Weaviate OSS before 1.33.4. An attacker with access to insert data into the database can craft an entry name with an absolute path (e.g., /etc/...) or use parent directory traversal (../../..) to escape the restore root when a backup is restored, potentially creating or overwriting files in arbitrary locations within the application's privilege scope.

An issue was discovered in Weaviate OSS before 1.33.4. Due to a lack of validation of the fileName field in the transfer logic, an attacker who can call the GetFile method while a shard is in the "Pause file activity" state and the FileReplicationService is reachable can read arbitrary files accessible to the service process.

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-8697-479h-5mfp. This link is maintained to preserve external references.

Original Description An issue in weaviate v.1.20.0 allows a remote attacker to cause a denial of service via the handleUnbatchedGraphQLRequest function.
