CVE-2025-58898 is a Remote File Inclusion (RFI) vulnerability found in the AncoraThemes HealthHub WordPress plugin, affecting versions up to and including 1.3.0. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements, allowing an attacker to supply a remote file path. When exploited, this flaw enables an attacker to execute arbitrary PHP code on the vulnerable server by including malicious remote files. The vulnerability requires no authentication and no user interaction, making it highly exploitable remotely over the network. The CVSS v3.1 score of 8.2 reflects a high impact on confidentiality (full data disclosure potential), with limited impact on integrity and no impact on availability. The flaw can lead to unauthorized disclosure of sensitive healthcare information, partial code execution, and potential pivoting within the network. Although no public exploits have been reported yet, the nature of RFI vulnerabilities makes them attractive targets for attackers aiming to compromise web servers. The vulnerability affects the HealthHub plugin, which is used to manage healthcare-related content and services on WordPress sites, increasing the risk profile due to the sensitivity of the data involved. The lack of available patches at the time of publication necessitates immediate mitigation efforts by administrators.

For European organizations, especially those operating healthcare websites or services using the AncoraThemes HealthHub plugin, this vulnerability poses a significant risk of data breaches involving sensitive patient information. Exploitation could lead to unauthorized disclosure of confidential health data, violating GDPR and other data protection regulations, resulting in legal and financial penalties. Additionally, attackers could execute arbitrary code, potentially gaining footholds in internal networks, leading to further lateral movement and compromise of critical infrastructure. The impact extends beyond data confidentiality to reputational damage and operational disruptions if attackers leverage the vulnerability to implant backdoors or malware. Given the high adoption of WordPress and related plugins in Europe, healthcare providers, clinics, and associated service providers are particularly vulnerable. The vulnerability's ease of exploitation without authentication increases the likelihood of automated scanning and attacks, amplifying the threat landscape for European entities.

1. Immediately update the AncoraThemes HealthHub plugin to a patched version once available. If no patch exists, consider disabling or uninstalling the plugin until a fix is released. 2. Implement strict input validation and sanitization on all parameters that influence file inclusion to prevent injection of remote file paths. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen directives to prevent inclusion of remote files. 4. Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block RFI attack patterns targeting PHP include/require statements. 5. Conduct thorough code audits of custom themes or plugins that interact with HealthHub to identify and remediate similar insecure coding practices. 6. Monitor web server logs for suspicious requests attempting to exploit file inclusion vulnerabilities. 7. Enforce the principle of least privilege on web server file permissions to limit the impact of potential code execution. 8. Educate development and security teams about secure coding practices related to file inclusion and remote content loading.
