Alert meAnalysisAIv1 – Jul 05, 2026
Arbitrary command execution in Pluck CMS 4.7.20-dev lets an authenticated administrator upload a crafted PHP file into the albums module directory and then invoke it through the routing logic in albums.site.php, passing OS commands via a GET parameter. The flaw stems from unrestricted file upload (CWE-434) combined with the module directory being directly web-accessible and PHP-executable, turning legitimate album management into a code-execution primitive. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, with a low EPSS probability of 0.51% (40th percentile).

DescriptionNVD
In Pluck CMS 4.7.20-dev, an authenticated attacker can upload or create a crafted PHP file under the albums module directory and access it via the module routing logic in albums.site.php, resulting in arbitrary command execution through a GET parameter.
Executive ViewAI
Pluck CMS 4.7.20-dev allows authenticated administrators to upload and execute arbitrary PHP code through the albums module, enabling operating-system-level command execution. Organizations using this CMS face potential complete system compromise if an administrator account is compromised or misused.
Within 24 hours: Inventory all Pluck CMS deployments and identify those running version 4.7.20-dev or later development builds. Within 7 days: Disable PHP execution in the albums and upload directories through web server configuration; restrict or disable album upload functionality. Within 30 days: Monitor vendor for patch availability and release timeline; evaluate migration to an actively maintained CMS platform as this appears to be a development version with unclear support status; implement MFA for all CMS administrator accounts.
Disable PHP execution in albums and upload directories via web server configuration (Apache .htaccess: php_flag engine off; Nginx: location block denying .php execution); validate all file uploads against image MIME types and file signatures; implement file integrity monitoring on upload directories; enforce multi-factor authentication for CMS administrator accounts; restrict CMS admin panel access to known IP addresses or VPN; enable and monitor all administrative activity logs.
