6.1.15
CVE-2025-54021 describes an Arbitrary File Access vulnerability within the Simple File List WordPress plugin. This vulnerability allows attackers to potentially read sensitive files on the server due to improper input validation. Versions of Simple File List between 0.0.0 and 6.1.14 are affected. A fix is available in version 6.1.15.
The vulnerability stems from a lack of proper input sanitization, allowing attackers to manipulate file paths and access files outside the intended directory. An attacker could leverage this to read configuration files, database credentials, or other sensitive data stored on the server. Successful exploitation could lead to data breaches, compromise of the WordPress installation, and potentially even remote code execution if sensitive files contain executable code or credentials for other systems. The impact is amplified in shared hosting environments where multiple websites share the same server resources.
CVE-2025-54021 was published on 2025-08-20. There are currently no known public exploits or active campaigns targeting this vulnerability. It is not listed on the CISA KEV catalog at the time of writing. The vulnerability's simplicity suggests a moderate likelihood of exploitation if a suitable exploit is developed and disseminated.
WordPress websites utilizing the Simple File List plugin, particularly those running older versions (0.0.0–6.1.14), are at risk. Shared hosting environments are especially vulnerable as they often have limited control over server configurations and file permissions. Sites with sensitive data stored on the server, such as database credentials or configuration files, face a higher potential impact.

The primary mitigation is to immediately upgrade Simple File List to version 6.1.15 or later. If upgrading is not immediately feasible, consider implementing a Web Application Firewall (WAF) rule to block requests containing path traversal sequences (e.g., ../). Additionally, restrict file permissions on sensitive files and directories to prevent unauthorized access. Regularly review WordPress plugin installations and remove any unused or outdated plugins to reduce the attack surface. After upgrading, confirm the vulnerability is resolved by attempting to access a file outside the intended directory via the plugin’s file listing functionality; access should be denied.
Actualice el plugin Simple File List a la última versión disponible para solucionar la vulnerabilidad de recorrido de directorio. Verifique las actualizaciones disponibles en el panel de administración de WordPress o a través del repositorio de plugins de WordPress. Asegúrese de realizar una copia de seguridad de su sitio web antes de actualizar cualquier plugin.
