CVE-2026-7043: Unrestricted Upload in GreenCMS
CVE-2026-7043 is a medium severity vulnerability in GreenCMS versions up to 2. 3 that allows unrestricted file upload via the pluginAddLocal function in the /index. php? m=admin&c=custom&a=pluginadd endpoint. This vulnerability can be exploited remotely without user interaction and affects only unsupported versions of GreenCMS. No official patch or remediation is available from the maintainer. The vulnerability has been publicly disclosed, but there are no confirmed exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability in GreenCMS (versions 2.0 through 2.3) involves the pluginAddLocal function in the admin custom plugin addition endpoint, which improperly restricts file uploads, allowing an attacker to upload arbitrary files remotely. The issue is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and CWE-284 (Improper Access Control). The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low complexity, no privileges required, no user interaction, and low impacts on confidentiality, integrity, and availability. The affected products are no longer supported by the maintainer, and no official fixes or patches have been released.
Potential Impact
Successful exploitation allows an attacker to upload arbitrary files to the affected GreenCMS installation, potentially leading to unauthorized code execution or other malicious activities depending on the uploaded file. Since the vulnerability requires no privileges or user interaction and can be triggered remotely, it poses a moderate risk. However, the impact is somewhat limited by the low confidentiality, integrity, and availability impacts indicated in the CVSS vector. The lack of vendor support means no official remediation is available.
Mitigation Recommendations
No official patch or remediation is currently available because the affected GreenCMS versions are no longer supported by the maintainer. Users should consider upgrading to a supported CMS platform or implementing external controls such as web application firewalls (WAFs) to restrict access to the vulnerable endpoint. Monitoring for suspicious file uploads and restricting file upload permissions at the server level may help mitigate risk. Patch status is not yet confirmed — check the vendor advisory or community resources for any updates or unofficial fixes.
