    Apache Storm UI: Stored Cross-Site Scripting (XSS) via Unsanitized Topology Metadata

    CVE-2026-35565 · GHSA-f2hp-qw27-8wfq

    Affected
    • Maven org.apache.storm:storm-webapp < 2.8.6
    Fixed in
    2.8.6· Vendor fix available
    Issue
    Stored Cross-Site Scripting (XSS) via Unsanitized Topology Metadata in Apache Storm UI Versions Affected: before 2.8.6 Description: The Storm UI visualization component interpolates topology metadata including component IDs, stream names, and grouping values directly into HTML via innerHTML in parseNode() and parseEdge() without sanitization at any layer. An authenticated user with topology submission rights could craft a topology containing malicious HTML/JavaScript in component identifiers (e.g., a bolt ID containing an onerror event handler). This payload flows through Nimbus → Thrift → the Visualization API → vis.js tooltip rendering, resulting in stored cross-site scripting. In multi-tenant deployments where topology submission is available to less-trusted users but the UI is accessed by operators or administrators, this enables privilege escalation through script execution in an admin's browser session. Mitigation: 2.x users should upgrade to 2.8.6. Users who cannot upgrade…

    Recommended action: Upgrade to 2.8.6 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
