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
Exposure of sensitive information due to incompatible policies issue exists in Pgpool-II. If a database user accesses a query cache, table data unauthorized for the user may be retrieved.

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 · moderate confidence

Pgpool-II's query cache feature does not properly enforce authorization policies, allowing database users to retrieve table data they are not authorized to access. When query caching is enabled, cached query results may be returned to users without proper validation against the user's actual permissions on the underlying tables.

MitigationReview and enforce proper access control policies on query cache configuration, or disable query caching if proper authorization cannot be ensured. Consider upgrading to a patched version if available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Pgpool-II installation and version
    Run 'psql -c "SELECT version();"' or check your package manager (dpkg -l | grep pgpool, rpm -qa | grep pgpool). Compare the version to any official Pgpool-II release notes for your distribution.
    Affected if The installed version is unpatched and older than the version that addresses this authorization bypass.
  2. Verify if query caching is enabled
    Check Pgpool-II configuration files (typically pgpool.conf) for 'query_cache' or 'memqcache' settings. You can also run 'SHOW query_cache;' or similar diagnostic command if available in your deployment.
    Affected if query_cache is set to 'on' or memqcache is configured and active.
  3. Inspect cache storage configuration
    Examine pgpool.conf for 'memqcache_method', 'memqcache_total_cache', and 'memqcache_max_cache' parameters. Check if shared memory or memory-based caching is in use.
    Affected if Memory-based query caching (memqcache) is actively storing query results.
  4. Review backend PostgreSQL user permissions
    Connect directly to the backend PostgreSQL databases as an administrator and audit SELECT permissions on sensitive tables using '\dp' or 'SELECT * FROM information_schema.table_privileges' for tables in databases served by Pgpool-II.
    Affected if Users have different permission levels between direct PostgreSQL access and access through Pgpool-II, indicating cached results may bypass checks.
  5. Test cache behavior with restricted data
    As a limited-privilege user, query a table you have access to through Pgpool-II, then verify the cached query. As a different user without permissions to that table, attempt the same query through Pgpool-II to see if cached results are returned.
    Affected if A user without table permissions receives cached data that was originally queried by a privileged user.

A user is affected if they run an unpatched Pgpool-II version with query caching enabled, and cached query results can be retrieved by users lacking proper table permissions.
