Remote code execution in OpenSearch Dashboards 3.0.0-3.7.x allows an authenticated low-privileged user to fully compromise the server via a prototype pollution flaw in the Time Series Visual Builder (TSVB) plugin. By sending a crafted JSON payload to the metrics visualization API endpoint, an attacker can corrupt the Node.js object prototype chain and achieve arbitrary server-side code execution. Vendor-released patch is available at version 3.8.0; no public exploit code or CISA KEV listing has been identified at time of analysis.
Unbounded HTTP request payload processing in OpenSearch Dashboards' capabilities route handler allows unauthenticated remote attackers to exhaust server resources and cause a denial of service. Affected products span both self-hosted OpenSearch Dashboards (all versions per CPE) and Amazon OpenSearch Service. The CVSS 4.0 score of 8.7 with AV:N/AC:L/AT:N/PR:N/UI:N reflects low attack complexity and no authentication prerequisite, making any network-exposed instance potentially reachable. No public exploit or CISA KEV listing has been identified at time of analysis, and a vendor-released patch is available.
