## Technical details

An authenticated remote code execution (RCE) vulnerability exists in Daylight Studio FuelCMS v1.5.2 within the Blocks module. The flaw is classified as a code injection vulnerability (CWE-94) where the application fails to properly neutralize or validate input used to generate code. An attacker with 'low' administrative privileges can leverage the network-reachable Blocks module to inject and execute arbitrary PHP code. This vulnerability allows for a total impact on confidentiality, integrity, and availability. While a proof-of-concept exists, the project is reportedly no longer in active development, and users are advised to migrate to supported platforms or implement strict access controls.
