CVE-2025-71395 (opens in a new tab)How to fix?
Upgrade surrealdb-core to version 2.0.5, 2.1.5, 2.2.2 or higher.
Overview
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value through the string::replace function. An attacker can exhaust server memory and cause a denial of service by crafting a query that uses a Regex to perform a string replacement, leading to unrestricted string length allocations.
Note:
This is only exploitable if the attacker has authenticated access to the database.
Workaround
This vulnerability can be mitigated by limiting the ability of untrusted clients to run the string::replace function using the --deny-functions flag or the SURREAL_CAPS_DENY_FUNC environment variable.
