CWEhttps://cwe.mitre.org/data/definitions/502.html

Incorrect parsing of certain JSON input may result in js-bson not correctly serializing BSON. This may cause unexpected application behaviour including data disclosure. This issue affects: MongoDB Inc. js-bson library version 1.1.3 and prior to.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Js-bson Mongodb * 1.1.4 (excluding)
Node-mongodb Ubuntu eoan *
Node-mongodb Ubuntu focal *
Node-mongodb Ubuntu trusty *

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
