CVE-2026-76783Network attack vector

Database query execution via sql parameter

Published Aug 20, 2026 · Updated Aug 20, 2026

SQL injection in /plus/advancedsearch.php in DedeCMS 53_1_UTF8 allows remote attackers to read or modify database data via the sql parameter. Public exploit material for the same endpoint shows that advancedsearch.php accepts a user-controlled sql value and treats attacker-supplied SQL as part of the backend query path instead of constraining it to a fixed search expression or safely parameterizing it. No authentication or user interaction is described in the CVE record, and the published proof-of-concept pattern demonstrates direct extraction of administrative data rather than host-level code execution.
