CVE-2026-44289

A flaw was found in protobufjs, a library that compiles protobuf definitions into JavaScript functions. A remote attacker could exploit this vulnerability by sending a specially crafted protobuf binary payload. This payload could cause uncontrolled recursion during the decoding of nested protobuf...

CVE-2026-44290

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...

CVE-2026-44291

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs used plain objects with inherited prototypes for internal type lookup tables used by generated encode and decode functions. If Object.prototype had already been polluted, those lookup table...
