{"id":"CVE-2026-107325","summary":"Application denial of service via missing BSON array length validation in MongoDB Go Driver","details":"Improper validation of a BSON array length in the MongoDB Go Driver can cause an out-of-bounds index and runtime panic when an application calls bson.RawArray.Validate or bsoncore.Array.Validate on a malformed four-byte array. An unauthenticated actor who can supply raw BSON array data to an affected application may terminate an unprotected application process, causing a denial of service. No confidentiality or integrity impact has been identified.","modified":"2026-10-29T02:48:31.067348393Z","published":"2026-10-08T19:01:01.894Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107325.json","unresolved_ranges":[{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"1.1.0"},{"fixed":"1.*"},{"introduced":"2.0.0"},{"fixed":"2.9.2"}]}]}],"cna_assigner":"mongodb","cwe_ids":["CWE-129"]},"references":[{"type":"WEB","url":"https://jira.mongodb.org/browse/GODRIVER-4136"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107325.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107325"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mongodb/mongo-go-driver","events":[{"introduced":"c6d13693a881560f3a85a1729e7f074c5f459c7d"},{"fixed":"df261dcb3f58dcedb9464bd8e7cd79f4e6657579"}],"database_specific":{"extracted_events":[{"cpe":"cpe:2.3:a:mongodb:go_driver:*:*:*:*:*:mongodb:*:*","range":[{"introduced":"2.0.0"},{"fixed":"2.9.2"}],"source":"CPE_RANGE"}]}}],"versions":["v2.9.1","v2.9.0","v2.8.0","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107325.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"}]}
