Description
Daylight Studio FuelCMS v1.5.2 was discovered to contain an authenticated remote code execution (RCE) vulnerability via the /controllers/Installer.php and the function add_git_submodule.
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the command injection flaw (CWE-77) in FuelCMS v1.5.2's Installer.php add_git_submodule function through timely patching or updates.
Prevents exploitation of the authenticated RCE by validating and sanitizing inputs to the vulnerable add_git_submodule function before command execution.
Mitigates risk by restricting access to the sensitive Installer.php functions to only users requiring privilege for git submodule operations, blocking low-privilege (PR:L) exploitation.
Security SummaryAI
CVE-2026-30461 is an authenticated remote code execution (RCE) vulnerability in Daylight Studio FuelCMS version 1.5.2. The flaw exists in the /controllers/Installer.php component, specifically within the add_git_submodule function, and stems from CWE-77 (command injection). Published on 2026-04-15, it carries a CVSS v3.1 base score of 8.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L), reflecting its high severity due to network accessibility, low attack complexity, and significant impacts on confidentiality and integrity.
An attacker with low-privilege authenticated access (PR:L) can exploit the vulnerability remotely over the network without user interaction. By abusing the add_git_submodule function, the attacker achieves arbitrary code execution on the server, enabling high-level compromise of confidentiality and integrity, alongside limited availability disruption.
