# CVE-2023-49657: Cross-site Scripting in Apache superset

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8% , percentile 57: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 57% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes apache-superset (PyPI) < 3.0.3, fixed in 3.0.3 . Check your lockfile, including transitive dependencies.

## What it is

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: TALISMANCONFIG = { "contentsecuritypolicy": { "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'"], }, "contentsecuritypolicynoncein": ["script-src"], "forcehttps": False, "sessioncookiesecure": False, }

## Affected packages

- PyPI `apache-superset` < 3.0.3 → fixed: 3.0.3

## Affected products (CVE record)

- Apache Software Foundation Apache Superset: < 3.0.3

## Severity

- apache CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.84% probability of exploitation activity in the next 30 days; percentile 57.
