CVE-2026-59876: Improperly Controlled Modification of Object Prototype Attributes

protobufjs compiles protobuf definitions into JavaScript JS functions. From 8.2.0 until 8.6.5, the protobufjs Text Format extension parsed string-keyed map entries using ordinary property assignment, allowing a map entry with key proto to change the prototype of the returned map object instead of...

CVE-2026-59877: Loop with Unreachable Exit Condition

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.6.5 and 8.6.6, protobufjs parsed option names by advancing through schema tokens until reaching an = token without checking for end of input, so a crafted .proto schema that opens an option declaration and ends...

protobufjs: protobufjs: Arbitrary code execution due to unsafe expression generation from crafted protobuf descriptors

A flaw was found in protobufjs, a library used to compile protobuf definitions into JavaScript functions. A remote attacker could exploit this vulnerability by providing a crafted descriptor that includes a non-string default value for a bytes field. This could lead to the generation of an unsafe...

CVE-2026-48712

A flaw was found in protobufjs. A remote attacker could exploit this by sending a crafted protobuf binary payload containing deeply nested 'Any' values. This uncontrolled recursion could exhaust the JavaScript call stack during conversion to JSON, leading to a Denial of Service DoS. Mitigation No...

CVE-2026-54270

A flaw was found in protobufjs. This library compiles protobuf definitions into JavaScript JS functions. A remote attacker could send a specially crafted protobuf payload containing numerous unknown fields. This could cause the decoded message to retain substantially more memory than expected,...

CVE-2026-54269

A flaw was found in protobufjs, a JavaScript JS library for compiling protobuf definitions. A remote attacker could exploit this vulnerability by providing specially crafted protobuf definitions or message types that contain names colliding with internal protobufjs runtime helpers. This could lea...

CVE-2026-54269

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 8.6.0 and 7.6.3, protobufjs accepted certain schema-derived names that could collide with properties used by protobufjs runtime helpers. The known affected names are fields named hasOwnProperty, field or oneof names...
