{"cve":"CVE-2026-29793","nvd":{"published":"2026-03-10T20:16:39.437","modified":"2026-06-17T10:29:53.880","status":"Analyzed","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-943"],"references":["https://github.com/feathersjs/feathers/security/advisories/GHSA-p9xr-7p9p-gpqx"],"products":["feathersjs:feathers"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-29793","score":0.00479,"percentile":0.4137,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-p9xr-7p9p-gpqx","url":"https://osv.dev/vulnerability/GHSA-p9xr-7p9p-gpqx","summary":"Feathers has a NoSQL Injection via WebSocket id Parameter in MongoDB Adapter","modified":"2026-03-13T04:22:19.452658Z","packages":[{"ecosystem":"npm","name":"@feathersjs/mongodb","purl":"pkg:npm/%40feathersjs/mongodb","ranges":[">=5.0.0 <5.0.42"],"fixed":["5.0.42"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
