NewCVE-2026-44635 (opens in a new tab)How to fix?
Upgrade kysely to version 0.28.17 or higher.
Overview
kysely is a Type safe SQL query builder
Affected versions of this package are vulnerable to SQL Injection via the visitJSONPathLeg function, which appends user-controlled values from .key() and .at() directly into single-quoted JSON path string literals without proper escaping. An attacker can inject arbitrary SQL by crafting input that breaks out of the JSON path string context.
Note: This is a bypass of the fix for the vulnerability described in CVE-2026-32763, which only escapes quote characters but not ., [, ], *, **, and ?.
