Global infos:

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, }
