"The version of MongoDB installed on the remote host is 7.0.x prior to 7.0.41, 8.0.x prior to 8.0.30, or 8.3.x prior
to 8.3.9. It is, therefore, affected by multiple vulnerabilities:

  - The $regexFindAll expression can be used by an authenticated user who can run aggregation pipeline stages
    to crash a MongoDB server (mongod). (CVE-2026-82052)

  - A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can
    retain stale authentication identities after user authentication under certain configurations, potentially
    permitting authenticated users to gain unintended elevated privileges through incorrect role assignments.
    (CVE-2026-82053)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
