Denial Of Service (DoS)

Wire is vulnerable to Denial of Service DoS. The vulnerability is due to improper validation of negative lengths in protobuf group-skipping logic, which allows an attacker to trigger an unchecked runtime exception and crash applications processing crafted protobuf payloads...

Wire: skipGroup() missing negative-length check allows 10-byte payload to crash any Wire-decoding service

CVE-2026-45799 Maintainer summary Wire's protobuf group-skipping logic did not reject negative lengths before skipping a length-delimited field inside a group. A crafted protobuf payload could cause Wire to throw an unchecked runtime exception during decoding instead of the documented IOException...
