CVE-2025-69407 identifies a Local File Inclusion (LFI) vulnerability in the Select-Themes Struktur PHP theme, affecting versions up to 2.5.1. The vulnerability arises from improper control over the filename parameter used in PHP's include or require statements, allowing an attacker to manipulate the input to include arbitrary files from the server. This can lead to disclosure of sensitive files such as configuration files, source code, or credentials, and may facilitate further attacks like remote code execution if combined with other vulnerabilities. The issue is classified as a PHP Remote File Inclusion type but specifically manifests as Local File Inclusion due to the improper validation of file paths. The vulnerability was reserved at the end of 2025 and published in early 2026, with no CVSS score assigned yet and no known exploits reported in the wild. The lack of patch links suggests that a fix may not yet be publicly available, increasing the urgency for users to implement temporary mitigations. The vulnerability impacts the confidentiality and integrity of affected systems and can be exploited without authentication, increasing its severity. Given the widespread use of PHP and WordPress themes globally, this vulnerability poses a significant risk to websites using the Struktur theme from Select-Themes.

The primary impact of CVE-2025-69407 is unauthorized disclosure of sensitive information through Local File Inclusion, which can expose configuration files, credentials, and source code. This can lead to further compromise, including privilege escalation and remote code execution if attackers chain this vulnerability with others. The integrity of the affected systems is at risk because attackers might manipulate included files or leverage the vulnerability to execute arbitrary code. Availability impact is generally lower but could occur if attackers disrupt normal operations by including malicious files. Organizations worldwide using the Struktur theme are at risk of data breaches, reputational damage, and potential regulatory penalties if sensitive data is exposed. The vulnerability's ease of exploitation without authentication and user interaction increases the likelihood of attacks, especially on publicly accessible web servers. The absence of known exploits currently provides a window for proactive mitigation, but the risk remains high due to the nature of the vulnerability and the popularity of PHP-based web applications.

To mitigate CVE-2025-69407, organizations should first check for and apply any official patches or updates from Select-Themes as soon as they become available. In the absence of patches, implement strict input validation and sanitization on all parameters used in include or require statements to ensure only intended files can be included. Employ whitelisting of allowable file paths and names to prevent arbitrary file inclusion. Disable PHP functions that are not required and can be exploited, such as allow_url_include, to reduce attack surface. Use web application firewalls (WAFs) to detect and block suspicious requests attempting file inclusion attacks. Regularly audit and monitor web server logs for unusual file access patterns. Consider isolating the web application environment using containerization or sandboxing to limit the impact of potential exploitation. Finally, educate development teams on secure coding practices to avoid similar vulnerabilities in future releases.
