Technical Analysis

The vulnerability CVE-2026-7044 exists in GreenCMS up to version 2.3 within the themeadd function located at /index.php?m=admin&c=custom&a=themeadd. It permits an attacker with limited privileges to upload files without restriction, potentially leading to unauthorized code execution or other impacts. The issue is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and CWE-284 (Improper Access Control). The vulnerability is remotely exploitable without user interaction. The affected GreenCMS versions are no longer supported by the vendor, and no official fix or patch is available.

Potential Impact

Successful exploitation of this vulnerability could allow an attacker to upload arbitrary files to the server, potentially leading to remote code execution or unauthorized access depending on the uploaded content and server configuration. Since the affected versions are unsupported, users remain exposed unless they upgrade or apply custom mitigations. There are no reports of widespread exploitation in the wild at this time.

Mitigation Recommendations

No official patch or remediation is currently available as the affected GreenCMS versions are no longer supported by the maintainer. Users should consider upgrading to a supported CMS or applying custom security controls to restrict file uploads and validate file types. Monitoring for suspicious uploads and restricting access to the themeadd function can help reduce risk. Patch status is not yet confirmed—check the vendor advisory or community sources for any updates.
