Subject: CVE-2023-49657: Apache Superset: Stored XSS in Dashboard Title and
 Chart Title 

Affected versions:

- Apache Superset through 3.0.3


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:

    "content_security_policy": {
        "base-uri": ["'self'"],
        "default-src": ["'self'"],
        "img-src": ["'self'", "blob:", "data:"],
        "worker-src": ["'self'", "blob:"],
        "connect-src": [
            """ ;,
            """ ;,
        "object-src": "'none'",
        "style-src": [
        "script-src": ["'self'", "'strict-dynamic'"],
    "content_security_policy_nonce_in": ["script-src"],
    "force_https": False,
    "session_cookie_secure": False,
