CVE-2025-62902 is a vulnerability identified in the ThemeHunk WP Popup Builder WordPress plugin, affecting all versions up to and including 1.3.6. The flaw allows an unauthenticated attacker to remotely retrieve embedded sensitive system information from the affected WordPress site. This exposure occurs because the plugin fails to properly restrict access to certain data or endpoints that contain sensitive configuration or system details. The vulnerability does not require any privileges or user interaction, making it easily exploitable over the network. The CVSS v3.1 score of 7.5 reflects a high severity primarily due to the confidentiality impact, as attackers can gain access to sensitive information that could include system paths, configuration parameters, or other data that aids in further exploitation. There is no impact on integrity or availability, meaning the vulnerability does not allow modification or disruption of services directly. No public exploits have been reported yet, but the ease of exploitation and the nature of the data exposed make it a significant risk. The vulnerability was published on October 27, 2025, and as of now, no official patches have been linked, indicating that users must be vigilant and consider temporary mitigations. The plugin is widely used in WordPress environments to create popup content, making it a common target for attackers seeking to gather information for subsequent attacks such as privilege escalation or lateral movement within compromised networks.

For European organizations, the exposure of sensitive system information can lead to increased risk of targeted attacks, including credential harvesting, phishing, and exploitation of other vulnerabilities discovered through the leaked data. Organizations running WordPress sites with the vulnerable WP Popup Builder plugin may inadvertently expose internal system details to attackers, undermining confidentiality and potentially facilitating further compromise. This is particularly critical for sectors with stringent data protection requirements, such as finance, healthcare, and government, where leakage of system information could lead to regulatory penalties under GDPR. Additionally, e-commerce and media companies relying on WordPress for customer engagement via popups may face reputational damage if attackers leverage this vulnerability to breach their systems. The lack of required authentication and user interaction means that attackers can automate exploitation at scale, increasing the threat surface. Although no known exploits are currently active, the vulnerability’s characteristics make it a likely candidate for future exploitation campaigns targeting European organizations with high WordPress usage.

European organizations should immediately inventory their WordPress installations to identify the presence of the ThemeHunk WP Popup Builder plugin and verify its version. Until an official patch is released, organizations should consider the following specific mitigations: 1) Restrict access to the plugin’s endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting known vulnerable paths. 2) Use server-level access controls (e.g., .htaccess rules) to limit exposure of sensitive plugin files or data to authenticated users only. 3) Monitor web server logs for unusual or repeated access attempts to the plugin’s resources, which may indicate exploitation attempts. 4) Disable or remove the plugin if it is not essential to reduce the attack surface. 5) Engage with the vendor or security community to obtain patches or workarounds as soon as they become available. 6) Conduct penetration testing focused on WordPress plugins to proactively identify similar vulnerabilities. 7) Educate site administrators on the importance of timely plugin updates and secure configuration practices. These measures go beyond generic advice by focusing on access restriction and active monitoring tailored to this specific vulnerability.
