{"id":"CVE-2026-19001","summary":"MongoDB BI Connector ODBC driver may write outside an allocated buffer when handling oversized catalog object names","details":"The MongoDB BI Connector ODBC Driver may write outside the bounds of a fixed-size buffer when an application supplies an unusually long catalog, schema, or object name to a metadata retrieval function. This may result in memory corruption within the calling application's process, leading to abnormal termination and, under certain conditions, the potential for arbitrary code execution.","modified":"2026-08-15T11:31:26.303622744Z","published":"2026-08-12T20:27:02.913Z","database_specific":{"cna_assigner":"mongodb","cwe_ids":["CWE-190"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/19xxx/CVE-2026-19001.json"},"references":[{"type":"WEB","url":"https://github.com/mongodb/mongo-bi-connector-odbc-driver/releases/tag/v1.4.9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/19xxx/CVE-2026-19001.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-19001"},{"type":"PACKAGE","url":"https://github.com/mongodb/mongo-bi-connector-odbc-driver"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mongodb/mongo-bi-connector-odbc-driver","events":[{"introduced":"f68c45f988f49a9db4b8cc6be90f3e33de1ddd8f"},{"fixed":"6c875f477f3c6b8f6b5620b80fd74f36678f3651"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"1.0.0"},{"fixed":"1.4.9"}]}}],"versions":["v1.4.8","v1.4.7","v1.4.6","v1.4.6-beta","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-19001.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:N"}]}
