How to Fix GHSA-wjjj-24cx-f28g

To remediate this vulnerability, upgrade all affected Surrealdb dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

surrealdb fixed: 3.1.0 
Upgrade surrealdb to 3.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for surrealdb

How to Check if You Are Affected

To determine whether your application is affected by GHSA-wjjj-24cx-f28g, inspect your project dependencies for Surrealdb:

inspect dependencies for surrealdb

Analyze the terminal output to locate any version of Surrealdb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-754: Improper Check for Unusual or Exceptional Conditions, where the product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product. In Surrealdb, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A single unauthenticated WebSocket message to `/rpc` crashed the SurrealDB server. Sending `use { db: "x" }` without first selecting a namespace hit `.expect("namespace should be set")` in the `use` handler; because `surrealdb-core` is built with `panic = 'abort'`, the panic terminated the process. `use` is callable before `signin`, and the per-method capability check passes by default for guest callers — so no credentials, token, or `--allow-guests` flag are required. ### Impact An unauthenticated remote attacker who could reach the `/rpc` endpoint could crash the SurrealDB server with a single WebSocket message. No credentials, token, session knowledge, or capability are required. ### Patches A patch has been introduced that returns a typed `invalid_params` response when `db` is set on a session with no `ns`, replacing the panic. - Versions 3.1.0 and later are not affected by this issue. ### Workarounds Affected users who are unable to update should restrict network access to the `/rpc` endpoint to trusted clients, and run SurrealDB under a process supervisor that restarts on crash.
