CVE-2025-11904Public exploitNetwork attack vector

Authenticated SQL injection via unvalidated id parameter

Published Oct 17, 2025 · Updated Oct 17, 2025

SQL injection in ChanCMS 3.3.0 through 3.3.2 allows remote authenticated users to alter database queries through the id parameter. The hasUse function at /cms/model/hasUse performs no validation on the id argument before database use, so SQL syntax supplied in that value changes the query. A valid administrative-panel session is required by the disclosed path; the public material does not identify which database records can be read or changed.
