CVE-2026-63302Network attack vector

Path disclosure via admin.php local file inclusion

Published Jul 28, 2026 · Updated Jul 28, 2026

Local file inclusion in OpenSolution Quick.CMS 6.8.0 and earlier allows remote authenticated users to disclose server paths. The admin.php endpoint uses the p parameter to select a local file for inclusion without adequately restricting attacker-controlled input. Administrative access is required, and inclusion is confined to the application's directory structure; the reported consequence is directory and absolute-path disclosure.
