CVE-2026-93765: Document deletion and process crash via unvalidated method-name dispatch in atomic pop operation
Critical · CVSS 9.1 (CVSS 3.1)EPSS 0.51%, 43th percentilePublished Updated Assigner: mongodb
Description
Mongoid contains an unsafe reflection weakness in the document persistence layer of its object-document mapping code. Input whose keys are passed through from an unauthenticated party by an embedding application can cause unintended internal method invocation instead of the intended array field update. This may result in unintended removal of stored records and in the embedding application becoming unresponsive.
