CVE-2026-48712 protobufjs: Denial of service through unbounded Any expansion during JSON conversion

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-2026-54270

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-2026-54270

CVE-2026-54270 concerns protobufjs, where versions 8.2.0–8.4.2 preserved unknown wire elements in message.$unknowns during binary decode and lacked a decode-time option to discard them. This could allow crafted protobuf payloads with many unknown fields to cause decoded messages to retain memory ...

CVE-2026-54271 protobufjs-cli: Code injection in pbjs static output from crafted JSON descriptor names

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...
