要点

CVE-2026-29793 は feathers (feathersjs), @feathersjs/mongodb に影響する深刻度「緊急」 (CVSS 9.8) の脆弱性です。
今後30日間に悪用される確率（EPSS）：0.48%（全脆弱性の 41.4% より高い）。
対処：5.0.42 以降に更新してください。

パッケージ	影響を受けるバージョン	修正済みバージョン
feathers feathersjs	`≥ 5.0.0, < 5.0.42`	`5.0.42`
@feathersjs/mongodb npm	`≥ 5.0.0, < 5.0.42`	`5.0.42`

概要

Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id matches every document in the collection.

NVD の説明

Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id matches every document in the collection. This vulnerability is fixed in 5.0.42.
