Drag and drop of data object from Parent Object to Child Object causing Memory Leak with Circular Data Reference

[benshen-secretlab]

Affected Version

2026.1

Affected capability

Data Objects

Steps to reproduce

Discussion Topic: https://github.com/orgs/pimcore/discussions/19218

1. Create Data Object with nested children
2. Drag parent object into child object
3. Refresh Data Object Tree
4. UI show loading, server side PHP process CPU run at 100% and took up all the available memory.
5. Data Indexing Messenger Crashed

Object Relation Reference Observation: object id 743 -> parent id 2 -> parent id 121 -> parent id 743
Tree Path: /PRODUCTS/Products/ITEMS/PRODUCTS/Products/ITEMS/% [Expected Path supposedly is /PRODUCTS/Products/ITEMS/%]

Actual Behavior

Server crash due to Circular Reference causing memory leak.
Need to restart server only able to tunnel into it.

Object Tree Refresh Endpoint:

• the process does not apply any PHP Memory Limit causing it took up all the available server memory.
