CVE-2026-44290: Improperly Controlled Modification of Object Prototype Attributes

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...

protobuf.js 输入验证错误漏洞

protobuf.js is a pure JavaScript implementation of the protobuf.js project, open source. It provides a protocol buffer implementation that supports Node.js and browsers with TypeScript. It’s easy to use, extremely fast, and can be used out of the box through.proto files. Versions of protobuf.js...

CVE-2026-44288: Improper Handling of Unicode Encoding

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs includes a minimal UTF-8 decoder that accepted overlong UTF-8 byte sequences and decoded them to their canonical characters instead of replacing them. An attacker who can provide protobuf...

CVE-2026-44292: Improperly Controlled Modification of Object Prototype Attributes

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-2026-44294: Improper Input Validation

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: Improper Control of Generation of Code

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs generated JavaScript for toObject conversion could include an unsafe expression derived from a schema-controlled bytes field default value. A crafted descriptor with a non-string default...
