Triggering this issue requires control over the server the driver connects to, or the ability to respond in its place, in order to return malformed metadata. The resulting memory corruption may cause the client application to terminate abnormally or, under certain conditions, execute unintended code.","published":"2026-08-12T21:17:37.000Z","lastModified":"2026-10-23T19:10:00.000Z","status":"Analyzed","sourceIdentifier":"cna@mongodb.com","cvss":{"version":"4.0","score":8.8,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-120"],"affected":["mongodb/bi connector odbc driver"],"epss":{"score":0.00404,"percentile":0.34358,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%).
