CVE-2026-44290

protobufjs compiles protobuf definitions into JavaScript (JS) functions.

Published May 13, 2026 · updated Jun 17, 2026 · protobufjs project protobufjs

protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs allowed certain schema option paths to traverse through inherited object properties while applying options. A crafted protobuf schema or JSON descriptor could cause option handling to write to properties on global JavaScript constructors, corrupting process-wide built-in functionality. This vulnerability is fixed in 7.5.6 and 8.0.2.
