CWE
- CWE-1321 - Improperly controlled modification of object prototype attributes ('prototype pollution')
Summary
Improper input validation in the Time Series Visual Builder (TSVB) plugin in OpenSearch Dashboards allows an authenticated remote user to execute arbitrary code on the server via a crafted JSON payload to the metrics visualization API endpoint. This issue is a form of prototype pollution that enables remote code execution.
To remediate this issue, users should upgrade to OpenSearch Dashboards 3.8 or later.
