DescriptionNVD

The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an out-of-bounds read).

The legacy GridFS API in the MongoDB C Driver fails to validate file metadata fields retrieved from the database, enabling crafted documents stored in a GridFS collection to trigger either a division-by-zero crash (denial of service) or an out-of-bounds read that exposes process memory contents to the caller. Versions in the 1.x branch before 1.30.8 and 2.x branch before 2.2.4 are affected per EUVD-2026-31132. …
