CVE-2026-54061: CWE-306: Missing Authentication for Critical Function in dgraph-io dgraph
Dgraph is an open source distributed GraphQL database. Prior to version 25.3.5, Dgraph Alpha exposes the RPCs used for external snapshot import on the public gRPC port `:9080` without authentication or authorization. As a result, an unauthenticated network client can open `StreamExtSnapshot` and send Badger stream data to the target group’s store. In addition, the receiver calls `Prepare()` before processing the stream. This operation deletes and replaces the existing DB data. Version 25.3.5 patches the issue.

Technical Summary
CVE-2026-54061 is a critical vulnerability in dgraph-io's Dgraph database prior to version 25.3.5. The Dgraph Alpha node exposes RPCs used for external snapshot import on the public gRPC port 9080 without authentication or authorization controls. An unauthenticated network client can invoke the StreamExtSnapshot RPC and send malicious Badger stream data to the target group’s store. The receiver executes a Prepare() call before processing the stream, which deletes and replaces the existing database data, leading to potential data loss or disruption. This vulnerability is fixed in version 25.3.5.
Potential Impact
An unauthenticated attacker can remotely cause data deletion and replacement in the Dgraph database by exploiting the exposed RPCs. This results in high impact on data integrity and availability, as the existing database content can be overwritten without any authentication barrier. Confidentiality is not impacted according to the CVSS vector, but integrity and availability are severely affected.
Mitigation Recommendations
Upgrade to Dgraph version 25.3.5 or later, where this vulnerability is patched. Since the vulnerability is fixed in this version, applying the official update is the recommended remediation. No other mitigation or temporary workaround is indicated in the available data.
