CVE-2026-93765: Document deletion and process crash via unvalidated method-name dispatch in atomic pop operation
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.

Event History
Frequently Asked Questions
Who is exposed to this issue?
Mongoid applications are exposed when an embedding application passes keys from an unauthenticated party into the affected atomic pop operation. The issue is in Mongoid's document persistence-layer method dispatch.
What does an attacker need to exploit it?
An attacker needs to supply input whose keys are passed through by the embedding application to the affected operation. No authentication or user interaction is required according to the provided severity vector.
What is the likely impact of successful exploitation?
Successful exploitation can invoke unintended internal methods rather than performing the intended array-field update. This can remove stored records and cause the embedding application to become unresponsive.
