CVSS 5.5 MEDIUM
A flaw was found in golang-protobuf. The protojson unmarshaling function can enter an infinite loop when parsing certain invalid JSON inputs, specifically when decoding messages containing Any values or when configured to discard unknown fields. A remote attacker can exploit this vulnerability by submitting specially crafted JSON payloads to cause excessive CPU utilization and hang the application, resulting in a Denial of Service (DoS).
