DescriptionGitHub Advisory

GetSimple CMS is a content management system. All versions of GetSimple CMS rely on .htaccess files to restrict access to sensitive directories such as /data/ and /backups/. If Apache AllowOverride is disabled (common in hardened or shared hosting environments), these protections are silently ignored, allowing unauthenticated attackers to list and download sensitive files including authorization.xml, which contains cryptographic salts and API keys. This issue does not have a fix at the time of publication.

AnalysisAI

Unauthenticated attackers can access sensitive files in GetSimple CMS when Apache's AllowOverride directive is disabled, bypassing .htaccess protections that restrict directory access. This configuration is common in hardened and shared hosting environments, exposing authorization credentials, API keys, and cryptographic salts in files like authorization.xml. Public exploit code exists for this vulnerability, and no patch is currently available.
