CVE-2025-46230 is a vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the GhozyLab Popup Builder plugin, versions up to and including 1.1.35. The flaw allows for PHP Local File Inclusion (LFI), a type of vulnerability where an attacker can manipulate the file path used in PHP include or require functions to load unintended files from the local filesystem. This can lead to unauthorized disclosure of sensitive files, such as configuration files, source code, or credentials stored on the server. Although the description references 'PHP Remote File Inclusion,' the actual issue is local file inclusion, meaning the attacker cannot directly include remote files but can exploit local files on the server. The vulnerability arises from insufficient validation or sanitization of user-supplied input that controls the filename parameter in the Popup Builder plugin. Exploiting this flaw requires the attacker to identify a vulnerable parameter that is passed to an include or require statement without proper checks. Once exploited, the attacker can read arbitrary files on the server, potentially escalating to code execution if combined with other vulnerabilities or misconfigurations. As of the published date (April 24, 2025), no patches or fixes have been released, and no known exploits are reported in the wild. The vulnerability is rated as medium severity, reflecting a moderate risk level given the potential impact and exploitation complexity. The Popup Builder plugin is commonly used in WordPress environments to create interactive popups, and its presence on websites increases the attack surface for this vulnerability. Since the vulnerability affects PHP-based web applications, it is relevant to organizations running WordPress sites with this plugin installed, especially those that handle sensitive user data or critical business functions.

For European organizations, the impact of CVE-2025-46230 can be significant, particularly for those relying on WordPress websites with the GhozyLab Popup Builder plugin. Successful exploitation can lead to unauthorized disclosure of sensitive internal files, including configuration files containing database credentials or API keys, which can facilitate further attacks such as database compromise or lateral movement within the network. The confidentiality of customer data, intellectual property, and internal communications may be at risk. Additionally, attackers might leverage the vulnerability to execute arbitrary PHP code indirectly if other vulnerabilities or misconfigurations exist, potentially leading to full system compromise. This can disrupt business operations, damage reputation, and result in regulatory non-compliance, especially under GDPR requirements for data protection. The medium severity rating indicates that while the vulnerability is exploitable, it requires some level of attacker knowledge and access to the vulnerable parameter. However, the widespread use of WordPress in Europe, including by SMEs and large enterprises, means that a substantial number of organizations could be exposed. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability becomes public knowledge. Organizations in sectors such as finance, healthcare, government, and e-commerce are particularly at risk due to the sensitive nature of their data and the attractiveness of their targets to threat actors.

Given the absence of official patches, European organizations should take immediate and specific mitigation steps beyond generic advice: 1. Audit and Inventory: Conduct a thorough inventory of all WordPress installations to identify instances of the GhozyLab Popup Builder plugin, especially versions up to 1.1.35. 2. Disable or Remove Plugin: Temporarily disable or remove the Popup Builder plugin from all affected systems until a patched version is available. 3. Input Validation: Implement web application firewall (WAF) rules to detect and block suspicious requests attempting to manipulate include or require parameters related to the plugin. Custom rules can be created to detect typical LFI attack patterns such as directory traversal sequences (e.g., ../). 4. Least Privilege: Ensure that the web server user has minimal file system permissions, restricting access to only necessary directories to limit the impact of any file inclusion attempts. 5. Monitoring and Logging: Enhance logging of web server and application events to detect anomalous access patterns or attempts to exploit file inclusion vulnerabilities. 6. Code Review: If customizations or extensions of the Popup Builder plugin exist, review the code for unsafe usage of include/require statements and sanitize all user inputs rigorously. 7. Network Segmentation: Isolate web servers hosting vulnerable plugins from critical internal networks to prevent lateral movement in case of compromise. 8. Stay Informed: Monitor vendor announcements and security advisories for the release of patches or updates addressing this vulnerability and apply them promptly. 9. Incident Response Preparedness: Prepare incident response plans to quickly address potential exploitation, including backup and recovery procedures.
