NewCVE-2026-48712 (opens in a new tab)How to fix?
Upgrade protobufjs to version 7.6.1, 8.4.1 or higher.
Overview
protobufjs is a protocol buffer for JavaScript (& TypeScript).
Affected versions of this package are vulnerable to Uncontrolled Recursion during the JSON conversion. An attacker can exhaust the call stack and cause the application to crash by supplying crafted protobuf binary data containing deeply nested Any values that are expanded during conversion. This is only exploitable if the application decodes attacker-influenced protobuf binary data, the schema includes google.protobuf.Any, the referenced type_url resolves to a loaded message type, and the application converts the decoded message to JSON or a plain object through an affected conversion path with deeply nested Any values.
