  • Not on the CISA list of exploited vulnerabilities.
  • No public exploit in Exploit-DB.

Is your app affected by CVE-2023-49657?

Paste this prompt into Claude Code, Cursor or any AI coding tool: it runs a free Shippable scan of your project and fixes what it finds. Built with Lovable, Bolt or v0? Scan your live app. Or upload your package file.

Who is affected

  • apache-superset (PyPI) < 3.0.3

How to check

  1. Run pip show apache-superset in your project to see the installed version, including copies pulled in by other packages.
  2. Or paste your lockfile into the checker: it lists every package with a known vulnerability, this one included.
  3. Or run npx shippable-dev scan localhost:3000 in your project folder. It reads your lockfile and flags this vulnerability along with every other known one.

How to fix

Copies a prompt for Claude Code, Cursor or Codex: it checks your lockfiles for this and upgrades it.
  1. Upgrade apache-superset to 3.0.3 or later, commit the lockfile and redeploy.
  2. If a vulnerable version was live, check your logs and rotate the secrets that server could read.

The advisory

A stored cross-site scripting (XSS) vulnerability exists in Apache Superset before 3.0.3. An authenticated attacker with create/update permissions on charts or dashboards could store a script or add a specific HTML snippet that would act as a stored XSS. For 2.X versions, users should change their config to include: TALISMAN_CONFIG = {     "content_security_policy": {         "base-uri": ["'self'"],         "default-src": ["'self'"],         "img-src": ["'self'", "blob:", "data:"],         "worker-src": ["'self'", "blob:"],         "connect-src": [             "'self'",             " https://api.mapbox.com" https://api.mapbox.com" ;,             " https://events.mapbox.com" https://events.mapbox.com" ;,         ],         "object-src": "'none'",         "style-src": [             "'self'",             "'unsafe-inline'",         ],         "script-src": ["'self'", "'strict-dynamic'"],     },     "content_security_policy_nonce_in": ["script-src"],     "force_https": False,     "session_cookie_secure": False, }

Check your whole app

Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
