Security readout for executives and security teams
CVE-2012-3871 is an authenticated cross-site scripting issue in Open Constructor CMS 3.12.0. A logged-in remote user could inject script or HTML through the header parameter in data/hybrid/i_hybrid.php. Business risk depends on whether this legacy CMS is still deployed and who can access that function. Exposure is most likely limited to organizations still running Open Constructor CMS 3.12.0 with authenticated users able to reach the vulnerable i_hybrid.php functionality. The bundle does not support claims about other versions or products. Treat this as a legacy-asset verification task. It is not currently evidenced as actively exploited, but an exposed outdated CMS with multiple users should be prioritized for upgrade, access restriction, or retirement. Mitigation focus: Inventory whether Open Constructor CMS 3.12.0 is deployed anywhere.; Restrict CMS access to trusted users and administrative networks where possible.; Check vendor or project guidance for a fixed version or official workaround..
