No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability was detected in volcengine OpenViking up to 0.3.21. This affects the function str_to_uint64 of the file openviking/storage/vectordb/utils/str_to_uint64.py of the component Local VectorDB Primary-key Label Handler. The manipulation of the argument ID results in insufficient verification of data authenticity. The attack may be launched remotely. Attacks of this nature are highly complex. The exploitability is reported as difficult. The pull request to fix this issue awaits acceptance.
