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...

CVE-2026-54270

protobufjs compiles protobuf definitions into JavaScript JS functions. From 8.2.0 to 8.4.2, protobufjs preserved unknown wire elements in message.$unknowns and did not provide a decode-time option to discard unknown fields before retaining them. A crafted protobuf payload containing many unknown...

CVE-2026-54271

protobufjs-cli is the command line add-on for protobuf.js. Prior to 1.3.2 and 2.5.0, a previous fix for unsafe name handling in pbjs static / static-module code generation was incomplete. Affected versions of protobufjs-cli could still emit unsafe JavaScript references when generating static outp...

CVE-2026-48712

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.6.1 and 8.4.1, protobufjs could recurse without a depth limit while converting decoded messages to plain objects or JSON. This affected generated toObject conversion and the custom google.protobuf.Any JSON conversio...

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...

CVE-2026-54269 protobufjs: Schema-derived names can shadow runtime-significant properties

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...

CVE-2026-54269

CVE-2026-54269 affects protobufjs. Prior to versions 8.6.0 and 7.6.3 , schema-derived names could collide with runtime helper properties (e.g., fields named hasOwnProperty, names like $type, and rpcCall). When loaded schemas are used, protobufjs could read schema-controlled data where an own-prop...
