Remote code execution in OpenSearch's SQL plugin cursor pagination component allows authenticated users holding only basic read/search permissions to execute arbitrary code on the server by supplying a crafted serialized cursor parameter to the plugins/sql endpoint. Affecting all versions of self-hosted OpenSearch and Amazon OpenSearch Service up to the patched releases, this CWE-502 deserialization flaw is particularly dangerous because the low privilege bar means any cluster user - not just administrators - can trigger it. Vendor-released patches exist in OpenSearch 2.19.6 and 3.7.0; no public exploit or CISA KEV listing has been identified at time of analysis.
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.
Remote code execution via the OpenSearch SQL plugin's Flint extension query handler exposes Apache Spark workers to arbitrary code execution by any authenticated user holding async query access. The vulnerable component is the SQL query validation layer in the Flint extension, which fails to prevent crafted payloads from reaching and executing on Spark worker nodes. No public exploit code has been identified at time of analysis, but the network-reachable RCE primitive, low complexity, and low privilege requirement collectively make this a high-priority remediation target; vendor patches are available in OpenSearch 3.7.0 and 2.19.6.
Server-side request forgery and local file read in the OpenSearch Security Analytics plugin exposes authenticated users with low privileges as a vector for internal network reconnaissance and credential theft. The flaw resides in the threat intelligence feed parser, which fails to validate URL parameters submitted to the threat intel source configuration endpoint, allowing a crafted request to redirect server-side HTTP fetches to internal resources - including cloud metadata endpoints. Patch is confirmed available per Amazon's security bulletin AWS-2026-079; no public exploit code has been identified at time of analysis.
Missing authorization in the Execute Monitor API of the Amazon OpenSearch Alerting plugin allows any authenticated remote user to read, modify, or delete arbitrary index data by supplying crafted inline monitor requests with attacker-controlled data source and input index parameters. The flaw bypasses index-level permission enforcement, making it a meaningful privilege escalation risk in multi-tenant or shared OpenSearch deployments. A vendor patch is available; no public exploit or CISA KEV listing has been identified at time of analysis.
Stored cross-site scripting in the OpenSearch Dashboards dashboards-observability plugin allows a remote authenticated user with write permissions to saved objects to inject arbitrary JavaScript that executes in other users' browser sessions. Affected deployments include both self-hosted OpenSearch Dashboards and Amazon OpenSearch Service (managed). The scope change (S:C) and high confidentiality/integrity impact make this particularly dangerous in multi-tenant environments where admin accounts may view attacker-controlled saved assets. No public exploit or CISA KEV listing has been identified at time of analysis; vendor-released patches are available in versions 3.4.0 and 2.19.0.
