CVE-2021-32609
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedApache Superset up to and including 1.1 does not sanitize titles correctly on the Explore page. This allows an attacker with Explore access to save a chart with a malicious title, injecting html (including scripts) into the page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCross-site scripting (XSS) vulnerability in Apache Superset versions up to 1.1 where chart titles on the Explore page are not properly sanitized, allowing injection of HTML and JavaScript through maliciously crafted chart titles by users with Explore access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine Apache Superset versionRun 'pip show apache-superset' or check the version in your package manager. If using a Docker deployment, check the image tag or run 'superset version' if available.Affected if The installed version is 1.1 or lower (any version up to and including 1.1).
-
Verify Explore functionality is accessibleLog in as a user with Explore access and navigate to the Explore page (typically /superset/explore/). Confirm the page loads and allows chart creation/editing.Affected if The Explore page is accessible and users can create or edit charts.
-
Inspect existing chart titles for malicious contentQuery the charts table in the Superset metadata database. Look for chart titles containing HTML tags (<script>, <img>, <iframe>, onerror, javascript:, etc.) or unusual character sequences that may indicate XSS payloads.Affected if Any chart title contains unsanitized HTML or JavaScript code that could execute in a browser.
-
Check database for stored XSS patternsRun a SQL query on the dashboards or slices table (depending on your Superset version) filtering for title fields with patterns like '<script', 'onerror=', 'javascript:', or other HTML/script tags.Affected if Chart or dashboard titles in the database contain raw HTML or JavaScript tags.
You are affected if you run Apache Superset version 1.1 or lower AND the Explore feature is accessible to users, regardless of whether malicious chart titles currently exist in your database.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Apache Superset to version 1.2 or later which contains the fix. If unable to upgrade, audit existing charts for malicious titles and implement input validation/sanitization on the Explore page before saving chart titles.
1.2 or later
- Upgrade Apache Superset to version 1.2 or later to obtain the fix for the XSS vulnerability in chart titles
