OpenSearch vulnerabilities

Improper input validation in the Vega expression function implementation in OpenSearch Dashboards allows a remote authenticated actor with dashboard write permissions to execute arbitrary JavaScript in the context of other users' browser sessions by saving a crafted Vega visualization. The checkForFunctionProperty validation routine failed to recurse into arrays of objects, allowing a function property nested inside an array to bypass validation.

Unrestricted deserialization of untrusted data in the cursor pagination component in the OpenSearch SQL plugin allows a remote authenticated user with basic read/search permissions to execute arbitrary code on the server by sending a crafted cursor parameter to the plugins/sql endpoint.

Improper input validation in the dashboards-observability plugin in OpenSearch Dashboards allows a remote authenticated user with write permissions to OpenSearch Dashboards saved objects to execute arbitrary JavaScript in the context of other users' browser sessions by uploading a saved asset with arbitrary web content.

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.

Improper input validation in the capabilities route handler in OpenSearch Dashboards - the size of the request payload is not bounded - might allow remote attackers to cause a denial of service via a crafted HTTP request.

A vulnerability in OpenSearch allows attackers to cause Denial of Service (DoS) by submitting complex query_string inputs. This issue affects all OpenSearch versions between 3.0.0 and < 3.3.0 and OpenSearch < 2.19.4.
