CVE-2026-32763Public exploitNetwork attack vector

SQL injection via unescaped JSON path legs

Published Mar 19, 2026 · Updated Mar 19, 2026

SQL injection in Kysely 0.26.0 through 0.28.11 allows remote attackers to read database data via crafted MySQL or SQLite JSON path keys. DefaultQueryCompiler.visitJSONPathLeg() inserts .key() and .at() values into single-quoted paths without escaping quotes, allowing injected SQL to leave the path literal. Reachability requires a consuming application to pass attacker-controlled values to these methods while bypassing Kysely's type restrictions.
