CVE-2025-53833: 
PHP vulnerability analysis and mitigation

LaRecipe, a widely-used documentation tool for Laravel applications with over 2.3 million downloads, has been found to contain a critical Server-Side Template Injection (SSTI) vulnerability (CVE-2025-53833). The vulnerability affects versions prior to 2.8.1 and has received a CVSS score of 10.0, indicating the highest severity level. The vulnerability was disclosed on July 14, 2025, and allows unauthenticated attackers to potentially execute arbitrary code on affected servers (GitHub Advisory, Security Online).

The vulnerability is classified as a Server-Side Template Injection (SSTI) flaw that could lead to Remote Code Execution (RCE) in vulnerable configurations. The issue has been assigned CWE-1336 (Improper Neutralization of Special Elements Used in a Template Engine). With a CVSS v3.1 base score of 10.0 (Critical) and vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H, the vulnerability requires no user interaction or privileges for exploitation (NVD).

The vulnerability's impact is severe, potentially allowing attackers to execute arbitrary commands on the server, access sensitive environment variables such as database credentials and API keys, and escalate privileges depending on server configuration. This poses a particularly significant risk for production environments where LaRecipe is publicly exposed or embedded in customer-facing platforms (GitHub Advisory, Security Online).

Users are strongly advised to upgrade to LaRecipe version 2.8.1 or later, which contains the necessary fix to eliminate the SSTI vulnerability. The patch has been released and is available for immediate deployment (GitHub Advisory).
