{"id":"CVE-2026-107324","summary":"Application denial of service via integer overflow in BSON value-length validation in MongoDB Go Driver","details":"An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. 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.","modified":"2026-10-29T02:48:31.066751153Z","published":"2026-10-08T18:58:01.098Z","database_specific":{"cna_assigner":"mongodb","cwe_ids":["CWE-190"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107324.json","unresolved_ranges":[{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"1.0.0"},{"fixed":"1.2.0"},{"introduced":"2.0.0"},{"fixed":"2.9.0"}]}]}]},"references":[{"type":"WEB","url":"https://jira.mongodb.org/browse/GODRIVER-4102"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107324.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107324"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mongodb/mongo-go-driver","events":[{"introduced":"1c3b9b9a41eecdf056560e07b68e6407b8d598c3"},{"fixed":"b414b897457665f12997cefd10ad934ccb9dfb3e"},{"introduced":"c6d13693a881560f3a85a1729e7f074c5f459c7d"},{"fixed":"099a81f05c516dc85ee25fffcc09000d547ba994"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"1.0.0"},{"fixed":"1.2.0"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:mongodb:go_driver:*:*:*:*:*:mongodb:*:*"},{"cpe":"cpe:2.3:a:mongodb:go_driver:*:*:*:*:*:mongodb:*:*","range":[{"introduced":"2.0.0"},{"fixed":"2.9.0"}],"source":"CPE_RANGE"}]}}],"versions":["v2.8.0","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107324.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"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"}]}
