MongoDB Server vulnerability

What happened

An issue in MongoDB Server's aggregation framework could allow an authenticated user to trigger an out-of-bounds memory read by providing a specially formed numeric parameter in a certain aggregation pipeline stage. This could result in a server crash (denial of service) and may potentially expose a limited amount of memory contents.

Affected versions

MongoDB Server: 8.3.0 through before 8.3.8 (semver); 8.0 through before 8.0.29 (semver); 7.0 through before 7.0.40 (semver) Fixed: See vendor advisory.
