Description

SurrealDB before 2.0.5, 2.1.x before 2.1.5, and 2.2.x before 2.2.2 does not enforce a default execution-time limit on embedded JavaScript scripting functions when the scripting capability is explicitly enabled (via --allow-scripting or --allow-all). An authenticated attacker can submit long-running JavaScript functions to exhaust server resources and cause a denial of service. Scripting is disabled by default.

• surrealdb: from 2.2.0 before 2.2.2 — fixed in 2.2.2

How to fix

Upgrade to a fixed version: surrealdb 2.0.5, 2.1.5, 2.2.2; surrealdb 2.2.2. Check the vendor advisory for mitigations.
