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...

CVE-2026-44291 protobufjs: Code generation gadget after prototype pollution

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...

CVE-2026-44291

CVE-2026-44291 affects protobufjs: prior to versions 7.5.6 and 8.0.2, internal type lookup tables used by generated encode/decode functions could be polluted via Object.prototype, allowing attacker-controlled inherited properties to influence protobuf type information and potentially emit attacke...
