CVE-2026-44521Network attack vector

Authenticated SQL injection via unvalidated target hash

Published May 27, 2026 · Updated May 27, 2026

SQL injection in Studio 42 Ltd. elFinder before 2.1.68 allows remote authenticated users to disclose MySQL data via a crafted target hash. The MySQL volume driver decodes the target file hash without validating its numeric object ID, then inserts the value into queries in cacheDir(), _joinPath(), _stat(), and _fopen(). Only installations using the MySQL driver are exposed; read-only volume access suffices, and broad queries can exhaust memory and interrupt service.
