HIGH 8.8

DescriptionNVD

Daylight Studio FuelCMS v1.5.2 was discovered to contain an authenticated remote code execution (RCE) vulnerability in the Blocks module.

AnalysisAI

Authenticated remote code execution in Daylight Studio FuelCMS version 1.5.2 allows low-privileged users to execute arbitrary code via the Blocks module. CVSS 8.8 rating indicates network-accessible attack requiring low-complexity exploitation without user interaction, enabling full system compromise (confidentiality, integrity, availability impact). No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).

Technical ContextAI

Improper authorization vulnerability in FuelCMS Blocks module permits authenticated users (PR:L) to bypass access controls and execute code server-side. Network vector (AV:N) with low attack complexity (AC:L) indicates straightforward exploitation path once authentication obtained. Root cause mechanism unspecified due to absent CWE classification.

RemediationAI

No vendor-released patch identified at time of analysis. Monitor official FuelCMS GitHub repository (https://github.com/daylightstudio/FUEL-CMS/) and vendor site (http://fuelcms.com) for security updates addressing CVE-2026-30460. Interim mitigations: restrict Blocks module access to trusted administrator accounts only, implement strict role-based access controls, disable Blocks functionality if not operationally required, deploy web application firewall rules to monitor POST requests to Blocks endpoints, audit existing user privileges and revoke unnecessary low-privilege accounts.
