CVE-2025-22509 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the TMRW-studio Atlas product up to version 2.1.0. This vulnerability is a form of Remote File Inclusion (RFI), where the application fails to properly validate or sanitize user-supplied input used in PHP include or require statements. Attackers can exploit this flaw by manipulating the filename parameter to include malicious remote files, which the PHP interpreter then executes. This can lead to arbitrary code execution on the server, allowing attackers to take control of the affected system, steal sensitive data, or pivot within the network. The vulnerability is notable because it does not require authentication or user interaction, making it easier to exploit remotely. Although no public exploits are currently known, the lack of patches and the critical nature of RFI vulnerabilities make this a significant threat. The vulnerability was reserved in early 2025 and published in 2026, indicating recent discovery and disclosure. The absence of a CVSS score suggests that detailed impact metrics are not yet available, but the technical nature of RFI vulnerabilities is well understood in the security community.

For European organizations, the impact of CVE-2025-22509 can be severe. Organizations running TMRW-studio Atlas on web servers are at risk of remote code execution, which can lead to full system compromise, data breaches, and disruption of services. This is particularly critical for sectors handling sensitive personal data under GDPR, such as healthcare, finance, and government institutions. Exploitation could result in unauthorized access to confidential information, defacement of websites, or use of compromised servers as a foothold for further attacks. The vulnerability's ease of exploitation without authentication increases the risk of widespread attacks, especially against internet-facing applications. Additionally, the lack of patches means organizations must rely on immediate mitigation strategies to reduce exposure. The reputational and regulatory consequences of a successful attack could be significant, including fines and loss of customer trust.

To mitigate CVE-2025-22509, organizations should immediately audit all PHP include and require statements in the Atlas application code to ensure that filenames are strictly validated and sanitized. Implement allowlists for file paths and disallow any user-controlled input from directly influencing include paths. Disable remote file inclusion in PHP configuration by setting 'allow_url_include' to 'Off' and 'allow_url_fopen' to 'Off' if not required. Employ web application firewalls (WAFs) to detect and block suspicious requests attempting to exploit file inclusion. Monitor logs for unusual file inclusion patterns or errors. If possible, isolate the Atlas application in a segmented network zone to limit potential damage. Stay alert for official patches or updates from TMRW-studio and apply them promptly once available. Additionally, conduct regular security assessments and penetration testing focused on file inclusion vulnerabilities.
