How to Fix GHSA-6r8p-hpg7-825g

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: 1.1.0 
Upgrade surrealdb to 1.1.0
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-6r8p-hpg7-825g, 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 1.1.0), 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-674: Uncontrolled Recursion, where the product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. 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

In some specific instances, the SurrealQL parser will attempt to recursively parse nested statements or idioms (i.e. nested `IF` and `RELATE` statements, nested basic idioms and nested access to attributes) without checking if the depth limit established by default or in the `SURREAL_MAX_COMPUTATION_DEPTH` environment variable is exceeded. This can lead to the stack overflowing when the nesting surpasses certain levels of depth. ### Impact An attacker that is authorized to run queries on a SurrealDB server may be able to run a query using the affected statements and idioms with very deep nesting in order to crash the server, leading to denial of service. ### Patches - Version 1.1.0 and later are not affected by this issue. ### Workarounds Concerned users unable to update may want to limit the ability of untrusted users to run arbitrary SurrealQL queries in the affected versions of SurrealDB. 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 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62410 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62652 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=63797 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=64445 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=64731 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=65277
