CSFLE and Queryable Encryption self-lookup may send malformed values in subpipelines

In MongoDB 7.3 prior to 7.3.4, a bug in query analysis of certain complex self-referential $lookup subpipelines may result in literal values in expressions for encrypted fields being sent to the server malformed.

Should this occur, no documents are returned or written. This issue affects the mongocryptd binary and mongo_crypt_v1 shared library in the following MongoDB Server versions:

  • 7.3.0 - 7.3.3

  • 7.0.0 - 7.0.11

  • 6.0.0 - 6.0.16

  • 5.0.0 - 5.0.28

Issues fixed:

  • SERVER-89529 Retryable writes during resharding may execute more than once if chunk migration follows the reshard operation

  • SERVER-91195 Provide a generic backportable solution not to miss top-level timeseries collection options

  • SERVER-91362 Do not copy JS "scope" object if a cached JsExecution exists

  • SERVER-91406 $changeStreamSplitLargeEvent returns Location7182803 error when used with non-renameable match expression

  • SERVER-91699 Subtracted memory greater than the total memory

  • All Jira issues closed in 7.3.4

  • 7.3.4 Changelog
