# CVE-2023-27524: Apache Superset Insecure Default Initialization of Resource Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Apache Superset. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-01-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-01-29 ; treat that as the outer limit, not the target.
- EPSS 97.4% , percentile 99.9: FIRST’s model estimates a 97.4% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

Session Validation attacks in Apache Superset versions up to and including 2.0.1. Installations that have not altered the default configured SECRETKEY according to installation instructions allow for an attacker to authenticate and access unauthorized resources. This does not affect Superset administrators who have changed the default value for SECRETKEY config. All superset installations should always set a unique secure random SECRETKEY. Your SECRETKEY is used to securely sign all session cookies and encrypting sensitive information on the database. Add a strong SECRETKEY to your supersetconfig.py file like: SECRETKEY = Alternatively you can set it with SUPERSETSECRETKEY environment variable.

## Affected products (CVE record)

- Apache Software Foundation Apache Superset: <= 2.0.1

## Severity

- apache CVSS 3.1: 8.9 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L`

## Exploitation

- CISA KEV: added 2024-01-08; federal due date 2024-01-29. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 97.41% probability of exploitation activity in the next 30 days; percentile 99.9.
