CVE-2026-44294

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs generated JavaScript property accessors from schema-controlled field and oneof names. Certain control characters in field names were not escaped before being embedded into generated functio...

CVE-2026-44293

CVE-2026-44293 affects protobufjs: prior to versions 7.5.6 and 8.0.2, generated JavaScript for toObject conversion could emit attacker-controlled code from a schema-controlled bytes field default value. A crafted descriptor with a non-string default for a bytes field may cause arbitrary JavaScrip...

CVE-2026-44292 protobufjs: Prototype injection in generated message constructors

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...

CVE-2026-44292

The CVE-2026-44292 issue affects protobufjs where generated message constructors copied enumerable properties from a provided object without filtering the proto key. This can let attackers pass an attacker-controlled plain object to a message constructor, causing per-instance prototype injection ...

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...

CVE-2026-44290

CVE-2026-44290 affects protobufjs, where certain schema option paths could traverse inherited properties during option processing, potentially corrupting process-wide built-in functionality. This vulnerability exists in versions prior to 7.5.6 and 8.0.2 and can enable a crafted protobuf schema or...
