Cross-namespace data modification via unguarded APPLYBATCH
Published Jun 25, 2026 · Updated Jun 25, 2026
Authorization failure in Apache Kvrocks 2.8.0 through 2.15.0 allows remote authenticated users to write arbitrary database data via APPLYBATCH. The APPLYBATCH command registration omits the admin attribute, so a namespace-authenticated client can submit a serialized RocksDB batch that the server applies without an administrator check. A namespace token and network access are required; successful exploitation can alter database state beyond the caller's authorized namespace.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
