CVE-2026-25464 is a Local File Inclusion (LFI) vulnerability found in the TieLabs Jannah WordPress theme, specifically affecting versions up to and including 7.6.3. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input to these statements, causing the server to include unintended local files. By exploiting this, an attacker can read sensitive files such as configuration files, password files, or other critical data stored on the server. In some cases, if combined with other vulnerabilities or misconfigurations, it could lead to remote code execution. The vulnerability does not require authentication or user interaction, making it easier for attackers to exploit remotely. No CVSS score has been assigned yet, and no known exploits are reported in the wild, but the nature of LFI vulnerabilities is well-understood and frequently targeted. The vulnerability affects a widely used WordPress theme, increasing the potential attack surface. The lack of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for immediate defensive measures. The issue was reserved in early February 2026 and published in late March 2026, indicating recent discovery and disclosure.

The impact of CVE-2026-25464 is significant for organizations using the TieLabs Jannah WordPress theme. Successful exploitation can lead to unauthorized disclosure of sensitive information, including server configuration files, database credentials, and user data, compromising confidentiality. Attackers may also leverage this vulnerability to execute arbitrary code on the server, leading to full system compromise, data tampering, or service disruption, affecting integrity and availability. Since the vulnerability does not require authentication or user interaction, it can be exploited remotely by unauthenticated attackers, increasing the risk of widespread attacks. Organizations hosting websites with this theme may face data breaches, defacement, or use of their infrastructure for further attacks. The reputational damage and potential regulatory penalties from data exposure can be severe. The absence of known exploits currently provides a window for proactive defense, but the vulnerability’s nature suggests it will be targeted soon. The broad use of WordPress and popular themes like Jannah means many small to medium businesses, bloggers, and enterprises could be affected globally.

1. Immediate action should be to monitor for an official patch from TieLabs and apply it as soon as it becomes available. 2. Until a patch is released, implement strict input validation and sanitization on any user-controllable parameters that influence file inclusion paths. 3. Employ a Web Application Firewall (WAF) with rules specifically designed to detect and block attempts to exploit LFI vulnerabilities, such as suspicious traversal sequences or unexpected file inclusion patterns. 4. Restrict PHP configuration settings by disabling allow_url_include and enabling open_basedir restrictions to limit file access scope. 5. Conduct a thorough audit of the affected web servers to identify any signs of compromise or unauthorized file access. 6. Educate development and security teams about secure coding practices to prevent similar vulnerabilities in custom themes or plugins. 7. Regularly back up website data and configurations to enable quick recovery in case of exploitation. 8. Consider temporarily disabling or replacing the Jannah theme if immediate patching is not feasible and the risk is unacceptable.
