CVE-2025-12550 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in the PHP program OchaHouse developed by jwsthemes. The vulnerability allows a Local File Inclusion (LFI) attack, where an attacker can manipulate the filename parameter in include or require statements to include arbitrary files from the server's filesystem. This can lead to disclosure of sensitive information such as configuration files, source code, or credentials, and in some cases, may allow execution of malicious code if combined with other vulnerabilities or writable file locations. The affected product, OchaHouse, is a PHP-based theme or content management system component, with versions up to and including 2.2.8 vulnerable. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely if the application is exposed to the internet. No CVSS score has been assigned yet, and no known exploits have been reported in the wild. The vulnerability was reserved in late 2025 and published in early 2026. The lack of patch links suggests that a fix may not yet be publicly available, increasing the urgency for organizations to apply mitigations. The vulnerability stems from insufficient validation or sanitization of user-supplied input used in file inclusion functions, a common PHP security issue. Attackers can leverage this to read sensitive files or escalate attacks, potentially compromising the confidentiality and integrity of affected systems.

For European organizations, the impact of CVE-2025-12550 can be significant, particularly for those relying on OchaHouse for website theming or content management. Exploitation could lead to unauthorized disclosure of sensitive data such as database credentials, configuration files, or user information, resulting in data breaches and compliance violations under GDPR. Additionally, attackers might use the vulnerability to execute arbitrary code or pivot within the network, leading to further compromise or service disruption. The ease of exploitation without authentication increases the risk of automated scanning and attacks, potentially affecting a wide range of organizations. This could impact sectors with high web presence such as e-commerce, media, and public institutions. The vulnerability could also damage organizational reputation and incur financial losses due to incident response and remediation costs.

Organizations should prioritize the following mitigations: 1) Monitor jwsthemes and OchaHouse vendor channels for official patches and apply updates promptly once available. 2) Implement strict input validation and sanitization on all parameters used in include/require statements to ensure only safe, expected file paths are processed. 3) Employ web application firewalls (WAFs) with rules designed to detect and block LFI attack patterns targeting PHP applications. 4) Restrict PHP file inclusion paths using configuration directives such as open_basedir to limit accessible directories. 5) Conduct thorough code reviews and security testing of customizations or integrations involving OchaHouse. 6) Regularly audit web server logs for suspicious requests attempting file inclusion exploits. 7) Consider isolating or containerizing web applications to limit the blast radius of potential exploitation. These measures go beyond generic advice by focusing on proactive detection, containment, and vendor-specific patch management.
