CVE-2020-13952
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 · uneditedIn the course of work on the open source project it was discovered that authenticated users running queries against Hive and Presto database engines could access information via a number of templated fields including the contents of query description metadata database, the hashed version of the authenticated users’ password, and access to connection information including the plaintext password for the current connection. It would also be possible to run arbitrary methods on the database connection object for the Presto or Hive connection, allowing the user to bypass security controls internal to Superset. This vulnerability is present in every Apache Superset version < 0.37.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn Apache Superset, authenticated users running queries against Hive and Presto database engines can access sensitive information through templated fields, including query description metadata, hashed user passwords, and plaintext connection passwords. The vulnerability also allows executing arbitrary methods on database connection objects, bypassing internal security controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Apache Superset versionRun 'pip show apache-superset' or check the version in your package manager to get the installed version numberAffected if Version is lower than 0.37.2 (e.g., 0.37.1, 0.36.x, etc.)
-
Identify Hive database connectionsNavigate to Data > Databases in the Superset UI or query the databases table in the metadata database to list configured connectionsAffected if Any Hive database connection exists in the environment
-
Identify Presto database connectionsNavigate to Data > Databases in the Superset UI or query the databases table in the metadata database to list configured connectionsAffected if Any Presto database connection exists in the environment
-
Check for templated queries using Jinja syntaxReview saved queries and explore the 'description' field or other templated fields that reference connection parameters or secretsAffected if Templated queries exist that reference sensitive fields like passwords or connection credentials
User is affected if running Apache Superset version below 0.37.2 AND has Hive or Presto database connections configured with templated queries that expose sensitive data.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data0.37.2
Upgrade Apache Superset to version 0.37.2 or later to patch the insecure templated field handling that exposes sensitive data and allows arbitrary method execution on database connections.
