Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Inconsistent object size validation in time series processing logic may result in later processing of oversized BSON documents leading to an assert failing and process termination. This issue impacts MongoDB Server v7.0 versions prior to 7.0.26, v8.0 versions prior to 8.0.16 and MongoDB server v8.2 versions prior to 8.2.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Inconsistent object size validation in MongoDB's time series processing logic allows oversized BSON documents to proceed through processing, eventually triggering an assertion failure that terminates the process. This is a denial of service vulnerability affecting time series collections.

MitigationUpgrade MongoDB Server to version 7.0.26+, 8.0.16+, or 8.2.1+ to patch the size validation inconsistency in time series processing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check MongoDB server version
    Run db.version() in the mongo shell or execute 'mongod --version' from command line
    Affected if Version is 7.0.0-7.0.25, 8.0.0-8.0.15, or 8.2.0 (all minor versions below 8.2.1)
  2. Identify time series collections
    Run db.getCollectionInfos({type: 'timeseries'}) in the mongo shell to list all time series collections in the database
    Affected if Any time series collections exist in the database AND the server version is in the affected range from step 1
  3. Verify time series bucket collection settings
    Inspect one time series collection with db.getCollection('your_timeseries_collection').stats() to confirm bucket configuration
    Affected if Collection is confirmed as time series type AND server version is in affected range

You are affected if your MongoDB server version falls within 7.0.0-7.0.25, 8.0.0-8.0.15, or 8.2.0 and you have time series collections in use, as oversized BSON documents in those collections can trigger the assertion failure.

Upgrade available Upgrade to 7.0.26 / 8.0.16 / 8.2.1 or later
Fixed in 7.0.268.0.168.2.1
Interim mitigation

Upgrade MongoDB Server to version 7.0.26+, 8.0.16+, or 8.2.1+ to patch the size validation inconsistency in time series processing.

Recommended fix High confidence

MongoDB 7.0.26 / 8.0.16 / 8.2.1 (minimum fixed version based on your branch)

  1. Determine your current MongoDB version using: db.version()
  2. Identify which version branch you are on (7.0.x, 8.0.x, or 8.2.x)
  3. For 7.0.x users: Upgrade to MongoDB Server 7.0.26 or later
  4. For 8.0.x users (prior to 8.2): Upgrade to MongoDB Server 8.0.16 or later
  5. For 8.2.x users: Upgrade to MongoDB Server 8.2.1 or later
  6. Backup your data before upgrading using mongodump
  7. Stop the MongoDB service gracefully
  8. Install the new version using your package manager or binary installation method
Caveat Review MongoDB release notes for your target version for any backward-incompatible changes; test upgrades in staging before production deployment
