An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.","state":0,"publishedAt":"2026-10-08T18:58:01.098+00:00","modifiedAt":"2026-10-08T19:31:13.465+00:00","affected":[{"ecosystem":"Vendor product","name":"Go Driver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MongoDB\",\n                    \"product\": \"Go Driver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.0\",\n                            \"lessThan\": \"1.2.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.0\",\n                            \"lessThan\": \"2.9.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://jira.mongodb.org/browse/GODRIVER-4102"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107324","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107324","identifiers":["CVE-2026-107324"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
