Release notes

Sourced from go.mongodb.org/mongo-driver/v2's releases.

MongoDB Go Driver 2.9.1

The MongoDB Go Driver Team is pleased to release version 2.9.1 of the official MongoDB Go Driver.

Release Highlights

[!WARNING]
Go Driver versions v1.0.0 through v1.17.9 and v2.0.0 through v2.9.0 are affected by a security issue CVE-2026-88031 in the GridFS delete methods. This release resolves that security issue in Go Driver v2. Users are encouraged to upgrade to Go Driver v2.9.1 as soon as possible. For the fix in Go Driver v1, see the v1.17.10 release.

This release addresses CVE-2026-88031, a security issue in GridFS delete methods where the file ID lookup could match more loosely than intended, potentially causing unintended file (and chunk) deletions instead of an exact match on the given file ID.

Users can manually restrict the file ID with a $eq operator before passing it to GridFSBucket methods using code like the following.

func exactMatch(id any) bson.D {
	return bson.D{{"$eq", id}}
}
// e.g., for v2, (*GridFSBucket).Delete() with an exact match on the file ID.
gridFSBucket.Delete(context.TODO(), exactMatch(id))
