How to Fix GHSA-h4f5-h82v-5w4r

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: 2.1.0 
Upgrade surrealdb to 2.1.0
surrealdb-core fixed: 2.1.0 
Upgrade surrealdb-core to 2.1.0
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-h4f5-h82v-5w4r, 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 2.1.0), 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-248: Uncaught Exception, where an exception is thrown from a function, but it is not caught. 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

The `rand::time()` function in SurrealQL generates a random time from an optional range of two Unix timestamps. Due to the underlying use of `timestamp_opt` from the `chrono` crate, this function could potentially return `None` in some instances, leading to a panic when `unwrap` was called on its result in order to return a SurrealQL `datetime` type to the caller of the function. ### Impact A client that is authorized to run queries in a SurrealDB server would be able to make repeated (in the order of millions) calls to `rand::time()` in order to reliably trigger a panic. This would crash the server, leading to denial of service. ### Patches The function has been updated in to guarantee that some `datetime` is returned or that an error is otherwise gracefully handled. - Version 2.1.0 and later are not affected by this issue. ### Workarounds Affected users who are unable to update may want to limit the ability of untrusted clients to run the `rand::time()` function in the affected versions of SurrealDB using security capabilities. To limit the impact of the denial of service, SurrealDB administrators may also want to ensure that the SurrealDB process is running so that it can be automatically re-started after a crash. ### References - #5126 - [SurrealQL Documentation - Database Functions (`rand::time`)](https://surrealdb.com/docs/surrealql/functions/database/rand#randtime) - [SurrealDB Documentation - Security Capabilities (Functions)](https://surrealdb.com/docs/surrealdb/security/capabilities#functions)
