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
SurrealDB versions before 3.2.0 contain a permissions bypass vulnerability where data-modifying statements within PERMISSIONS clauses execute with enforcement disabled. Attackers with permission to perform a guarded operation can write to tables they lack permission for by embedding CREATE, UPDATE, DELETE, or UPSERT statements in the PERMISSIONS clause, causing unintended writes and data corruption.

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 2026-08-03.

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.

Upgrade available Upgrade to 3.2.0 or later
Fixed in 3.2.0
Recommended fix Moderate confidence

3.2.0

  1. Check current Surrealdb version using `surreal --version` or checking the running container image tag
  2. Back up all database data and configuration files before upgrading
  3. For Docker deployments: Update the image tag in your docker-compose.yml or deployment config to `surrealdb:3.2.0` or later, then recreate containers with `docker-compose up -d`
  4. For package manager installations: Run `apt-get update && apt-get install surrealdb` or the equivalent for your package manager
  5. For binary installations: Download the 3.2.0 or later release from the official Surrealdb GitHub releases page
  6. After upgrading, verify the version is 3.2.0 or higher with `surreal --version`
  7. Test that PERMISSIONS clauses no longer execute embedded data-modifying statements by attempting the documented attack vector in a test environment
  8. Monitor logs for any authorization errors to confirm the fix is functioning
