CVE-2026-53952 Sep 11, 19:23 CRITICAL Act Now

Unauthenticated administrator account creation affects GetSimple CMS (v3.4.0a and earlier) and its community edition GetSimpleCMS-CE (v3.3.22 and earlier), where a self-exclusion bug in the post-installation cleanup logic leaves admin/setup.php reachable on production sites. Any remote attacker can invoke the still-present setup script to register a new administrator, yielding full control of the CMS. No patched version exists at publication and no public exploit has been identified, though the flaw is trivially reproducible from the advisory description.
