Why this deserves its current priority

CVSS is 2.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Analysis status

Analysis pending evidence review

Factual feed record only; HOL analysis is not approved for indexing. Read the methodology.

Affected scope and exposure questions

The current feed maps MongoDB/MongoDB Server (generic). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for MongoDB/MongoDB Server.
  2. 2Review the reported fix. Update MongoDB/MongoDB Server to 9.0.7 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

  • Source referencejira.mongodb.org
Upstream source description

In MongoDB Server, an authenticated user with insert privileges on a collection could craft a command with specially constructed encryption-related parameters to redirect internal Queryable Encryption metadata writes to metadata belonging to other encrypted collections within the same database. The server’s authorization layer validated only the user-facing target collection namespace, while subsequent internal writes derived from client-supplied parameters were performed with elevated internal privileges, bypassing the original caller’s permission scope. This could allow unauthorized writes into another collection’s Queryable Encryption metadata, potentially corrupting encrypted index state and compaction operations.
