Title

SurrealDB before 1.0.1 Insecure Default Table Permissions

Summary

SurrealDB before 1.0.1 sets default table permissions to FULL instead of NONE, allowing SELECT, CREATE, UPDATE, and DELETE operations on tables without explicit permissions. Attackers with database access or unauthenticated users on publicly exposed instances can perform unrestricted operations on unprotected tables within their authorization scope.

GHSA-X5FR-7HHJ-34J3

Vulnerability from github – Published: 2023-12-15 03:46 – Updated: 2026-09-04 18:27

Summary

SurrealDB: Full Table Permissions by Default

Details

Default table permissions in SurrealDB were FULL instead of NONE. This would lead to tables having FULL permissions for SELECT, CREATE, UPDATE and DELETE unless some other permissions were specified via the PERMISSIONS clause.

We have decided to treat this behaviour as a vulnerability due to its security implications, especially considering the lack of specific documentation and potential for confusion due to the INFO FOR DB statement previously not displaying default permissions. Treating it as a bug fix provides justification for a change in default behavior outside of a major release.

Impact

Any client authorized to query data in a SurrealDB instance will have full access to any tables that were defined with no explicit permissions and that are within its authorization scope (i.e. namespace or database), including creating, reading, updating and deleting data. This is specially relevant for SurrealDB instances allowing guest access with publicly exposed interfaces (e.g. HTTP REST API or WebSocket API), since a remote unauthenticated user may gain full access to any tables that were defined without any explicit permissions. Tables that were defined with explicit permissions using the PERMISSIONS clause are not affected.

Patches

Version 1.0.1 includes a patch for this specific issue. Later releases will also include the patch.
Version 1.1.0-beta.1 and latest nightly releases already include the patch for this issue.

In patched versions:

Tables defined after the patch without explicit permissions have NONE permissions.
Table permissions are always explicitly displayed with the INFO FOR DB statement.

Workarounds

In unpatched versions, this issue can be resolved by explicitly defining table permissions as shown in the following examples:

-- INSECURE EXAMPLE
-- DEFINE TABLE insecure;
-- SECURE EXAMPLE 1
DEFINE TABLE secure PERMISSIONS NONE;
-- SECURE EXAMPLE 2
DEFINE TABLE secure PERMISSIONS FOR SELECT, CREATE, UPDATE, DELETE NONE;
-- SECURE EXAMPLE 3
DEFINE TABLE secure PERMISSIONS FOR
  SELECT WHERE user = $auth.id,
  CREATE, UPDATE, DELETE NONE;
-- SECURE EXAMPLE 4
DEFINE TABLE secure PERMISSIONS
  FOR select WHERE published = true OR user = $auth.id
  FOR create, update WHERE user = $auth.id
  FOR delete WHERE user = $auth.id OR $auth.admin = true;

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
