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.

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 · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-07-30.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Recommended fix High confidence

PostgreSQL 12.20, 13.16, 14.13, or 15.8 (depending on current major version)

  1. 1. Identify the current PostgreSQL version of your Azure Database for PostgreSQL Flexible Server by checking the server properties in Azure Portal or using Azure CLI: `az postgres flexible-server show --resource-group <rg> --name <server>`
  2. 2. Determine the appropriate target version based on your current major version (12.x → 12.20, 13.x → 13.16, 14.x → 14.13, 15.x → 15.8)
  3. 3. Review the server's maintenance window settings and ensure it is configured (Azure Portal → Server → Maintenance)
  4. 4. Create a point-in-time restore backup of your database before upgrading, using Azure Portal or CLI: `az postgres flexible-server restore --restore-time <time> --source-server <source> --target-server <target> --resource-group <rg>`
  5. 5. Initiate the engine version upgrade via Azure Portal (Server → Overview → Server Version → Check for upgrade) or Azure CLI: `az postgres flexible-server update --resource-group <rg> --name <server> --version <target-version>`
  6. 6. Monitor the upgrade operation status; the server may be unavailable during the upgrade process
  7. 7. After upgrade completes, verify the new version: `az postgres flexible-server show --resource-group <rg> --name <server>` and test application connectivity
Caveat Minor version upgrades in Azure Database for PostgreSQL are generally non-breaking but may require brief downtime; test in staging environment first
