CVE-2024-58366 · Severity: high · CVSS 8.5 · Published 2026-07-18

SurrealDB is a cloud-native database that supports advanced scripting functions. A vulnerability in its scripting engine allows users with script-execution privileges to trigger a memory error by providing specially crafted text. This could allow an attacker to read sensitive information from the server's memory or potentially take full control of the database process.

## Technical details

A format string vulnerability (CWE-134) exists in the rquickjs crate, which provides Rust bindings for the QuickJS engine used by SurrealDB. The Exception::throw_type function incorrectly passed user-controlled error strings directly to a printf-style function without proper sanitization. An attacker with permissions to define or execute scripting functions can provide inputs containing format specifiers (e.g., %s, %x) to trigger undefined behavior. This can be leveraged to leak process memory or achieve remote code execution (RCE), though RCE complexity is increased by Rust's default exploit mitigations and a 256-byte limit on error messages. The vulnerability is only exploitable if scripting is explicitly enabled via --allow-scripting or --allow-all.

## Affected products

- SurrealDB SurrealDB < 1.1.1
