An application that builds such a document from user-supplied field names can have the server apply update operators instead of a full replacement. The effect is limited to the document matched by the application's own filter, whose contents can be modified in ways the application did not intend.","categories":["Databases"],"product":"C# Driver","vendor":"MongoDB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114647","source_modified_at":"2026-10-22T21:25:33.454Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"C# Driver","vendor":"MongoDB","versions":[{"status":"affected","version":"2.13.0","lessThan":"3.13.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114647","source_modified_at":"2026-10-22T21:25:33.454Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"C# Driver","ecosystem":null},"version":"3.13.0","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00259,"percentile":0.16615,"score_date":"2026-10-23"},"published_at":"2026-10-22T19:13:51.972Z","modified_at":"2026-10-22T21:25:33.454Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114647","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-22T21:25:33.454Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114647","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://jira.mongodb.org/browse/CSHARP-6186"},{"source":"CVE List","url":"https://github.com/mongodb/mongo-csharp-driver/releases/tag/v3.13.0"},{"source":"CVE List","url":"https://github.com/mongodb/mongo-csharp-driver/security/advisories/GHSA-68cj-624m-mxj3"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-22T21:25:33.454Z","content_hash":"f35cf7d4109bd1c0a22ad01da628b3f3135c13b04120edb8db0fe363e52488ec"}}
