CVE-2025-39360 is a vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the 'Grace Mag' theme developed by everestthemes, versions up to and including 1.1.5. The flaw allows for PHP Local File Inclusion (LFI), a type of vulnerability where an attacker can manipulate the filename parameter in an include or require statement to execute arbitrary files on the server. Although the description mentions 'PHP Remote File Inclusion' in the title, the actual impact is local file inclusion, meaning the attacker can include files already present on the server rather than fetching remote files. This can lead to unauthorized disclosure of sensitive files, execution of arbitrary PHP code, or even privilege escalation if exploited successfully. The vulnerability arises due to insufficient validation or sanitization of user-supplied input used in the include/require statements, allowing an attacker to traverse directories or specify unintended files. No patches or fixes have been linked yet, and there are no known exploits in the wild as of the publication date (April 24, 2025). The vulnerability was reserved on April 16, 2025, and has been enriched by CISA, indicating recognition by US cybersecurity authorities. The affected product, Grace Mag, is a WordPress theme, which suggests that the vulnerability primarily impacts websites using this theme, potentially exposing them to code execution or data leakage risks.

For European organizations, the impact of this vulnerability could be significant, especially for those relying on WordPress sites using the Grace Mag theme. Exploitation could lead to unauthorized access to sensitive data stored on web servers, including configuration files, user credentials, or proprietary information. Attackers could also execute arbitrary PHP code, potentially leading to full site compromise, defacement, or use of the server as a pivot point for further attacks within the organization's network. This could disrupt business operations, damage reputation, and lead to regulatory non-compliance, particularly under GDPR, if personal data is exposed. The medium severity rating reflects that while exploitation requires some knowledge of the target and the presence of the vulnerable theme, the consequences can be severe if successful. Since the vulnerability does not require remote file inclusion, the attack surface is somewhat limited to local files, but the lack of authentication requirements or user interaction details is not explicitly stated, so the risk remains notable. Organizations with public-facing websites using this theme are at higher risk, especially those in sectors like media, publishing, or e-commerce where WordPress themes are commonly deployed.

1. Immediate audit of all WordPress installations to identify the use of the Grace Mag theme, particularly versions up to 1.1.5. 2. Disable or remove the Grace Mag theme from production environments until a patch or update is released by everestthemes. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests attempting directory traversal or unusual include parameter manipulations targeting PHP files. 4. Restrict file system permissions on web servers to limit the PHP process's access to sensitive files, reducing the impact of potential LFI exploitation. 5. Monitor web server logs for anomalous requests that may indicate attempts to exploit this vulnerability, such as requests containing directory traversal sequences (e.g., ../) or unusual query parameters. 6. Engage with the theme vendor or community to track the release of patches and apply them promptly once available. 7. Consider deploying runtime application self-protection (RASP) solutions that can detect and block malicious PHP code execution attempts. 8. Educate web administrators and developers about secure coding practices, particularly validating and sanitizing inputs used in include/require statements to prevent similar vulnerabilities.
