When an application reads a sufficiently large floating point value as text, the driver may write beyond the end of that buffer and corrupt adjacent memory. A user who can store data in a collection read through the BI Connector could use this to crash the application performing the read.","published":"2026-08-12T21:17:37.170","modified":"2026-08-12T21:17:37.170","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/mongodb/mongo-bi-connector-odbc-driver/releases/tag/v1.4.9"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T21:17:37.170"}}
