Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A Regular Expression Denial of Service (ReDoS) vulnerability exists in Apache Superset versions 1.5.0 through 5.0.0. The vulnerability is located in the sql_parse.py component, specifically within the SQL_REGEX used for parsing SQL statements in the sqlparse library integration. The affected regular expression contains overlapping disjunctions that share a common outer quantifier. An authenticated attacker can exploit this by sending a maliciously crafted input string (specifically a long sequence of backslashes or similar characters) to endpoints that process SQL queries This issue affects Apache Superset: before 6.0.0. Users are recommended to upgrade to version 6.0.0, which fixes the issue.  Workarounds: ● WAF Rules: Implement Web Application Firewall (WAF) rules to detect and block requests containing excessively long sequences of backslashes or suspicious repeated patterns in the queries.extras.where parameter. ● Rate Limiting: Ensure strict rate limiting is applied to the /api/v1/chart/data endpoint to reduce the impact of potential attacks.

Fixed in 6.0.0
Recommended fix High confidence

apache-superset version 6.0.0

  1. 1. Back up all Superset data, configuration files, and databases before upgrading
  2. 2. Identify the current installation method used (pip, docker, helm, or source)
  3. 3. If using pip: run 'pip install apache-superset==6.0.0' to upgrade to the fixed version
  4. 3. If using Docker: pull the new image tag 'apache/superset:6.0.0' and redeploy the container
  5. 3. If using Kubernetes/Helm: update the helm chart to use version 6.0.0 and upgrade the release
  6. 4. Run database migrations if required: 'superset db upgrade'
  7. 5. Restart all Superset services to load the updated version
  8. 6. Verify the upgrade was successful by checking the Superset version in the UI or via CLI: 'superset version'
Caveat Review the 6.0.0 release notes for any breaking changes, especially regarding database migrations, deprecated features, and any required configuration updates for custom plugins or integrations
