EPSS

• CVE-2023-49657: 0.84% estimated exploitation activity in the next 30 days; percentile 57.80 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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, }

# Patch Next advisory brief: CVE-2023-49657

Advisory: Cross-site Scripting in Apache superset
IDs: CVE-2023-49657, GHSA-rwhh-6x83-84v6
Record: https://patchnext.com/advisories/cve-2023-49657 (revision 4, source checked 28 Oct 2026, 06:10 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: apache-superset 3.0.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI apache-superset: affected < 3.0.3; fixed in 3.0.3

## Suggested inspection (read-only)
- `python -m pip show apache-superset`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on apache-superset.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
