CVE-2025-49370 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the AncoraThemes Lymcoin product up to version 1.3.12. This vulnerability allows a Remote File Inclusion (RFI) attack vector, where an attacker can manipulate the filename parameter used in PHP include or require statements to load arbitrary files. The vulnerability stems from insufficient validation or sanitization of user-supplied input that determines which files are included by the PHP application. By exploiting this flaw, an attacker can cause the application to include malicious remote files or local files containing sensitive information, leading to arbitrary code execution on the server. This can result in full system compromise, data theft, defacement, or pivoting within the network. The vulnerability does not require authentication, making it accessible to unauthenticated attackers, and does not require user interaction beyond sending crafted HTTP requests. Although no known exploits are currently reported in the wild and no patches have been released, the vulnerability is publicly disclosed and should be treated with urgency. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. AncoraThemes Lymcoin is a WordPress theme product, commonly used in e-commerce and business websites, which increases the attractiveness of this vulnerability to attackers. The vulnerability's exploitation could disrupt availability, compromise confidentiality, and undermine integrity of affected systems.

For European organizations, the impact of CVE-2025-49370 can be significant, especially for those relying on AncoraThemes Lymcoin themes for their websites or e-commerce platforms. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to take control of web servers, access sensitive customer data, inject malware, or deface websites. This can result in reputational damage, regulatory penalties under GDPR due to data breaches, and operational downtime. Organizations in sectors such as retail, finance, and government that use Lymcoin themes are particularly vulnerable. The attack vector does not require authentication, increasing risk from external threat actors. Additionally, compromised servers can be used as pivot points for lateral movement within corporate networks, amplifying the threat. Given the public-facing nature of web themes, the attack surface is broad, and automated scanning tools can easily detect vulnerable installations. The absence of patches means organizations must rely on mitigations until official fixes are available, increasing exposure time.

1. Immediately audit all web applications using AncoraThemes Lymcoin themes to identify affected versions (<=1.3.12). 2. Apply strict input validation and sanitization on all parameters used in include/require statements to prevent injection of arbitrary file paths. 3. Implement allowlists for file inclusion paths to restrict included files to trusted directories only. 4. Disable remote file inclusion in PHP configuration by setting 'allow_url_include' to 'Off' and 'allow_url_fopen' to 'Off' where possible. 5. Monitor web server logs and network traffic for suspicious requests attempting to exploit file inclusion. 6. Employ Web Application Firewalls (WAFs) with rules targeting RFI attack patterns to block malicious requests. 7. Isolate and harden web servers hosting vulnerable themes to limit impact in case of compromise. 8. Plan for timely patching once official updates are released by AncoraThemes. 9. Educate development and security teams about secure coding practices related to file inclusion. 10. Consider temporary removal or replacement of vulnerable themes if immediate patching is not feasible.
