NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs generated message constructors copied enumerable properties from a provided properties object without filtering the proto key. If an application constructed a message from an attacker-controlled plain object, an own enumerable proto property could alter the prototype of that individual message instance. This vulnerability is fixed in 7.5.6 and 8.0.2.
