CVE-2025-62902 identifies a vulnerability in the ThemeHunk WP Popup Builder WordPress plugin, specifically versions up to 1.3.6. The flaw allows an unauthorized control sphere—meaning an attacker without proper privileges—to retrieve embedded sensitive system information from the plugin. This exposure can include configuration details, system paths, or other data embedded within the plugin that should not be accessible to unauthenticated users. The vulnerability arises from improper access controls or insufficient validation on endpoints or data retrieval functions within the plugin. Although no known exploits have been reported in the wild, the information disclosure can facilitate further attacks such as targeted exploitation, privilege escalation, or social engineering. The vulnerability was reserved and published in late October 2025, but no patch links are currently available, indicating that a fix may still be pending or in development. The absence of a CVSS score requires an assessment based on the potential impact and exploitability. Since the vulnerability allows unauthorized access to sensitive data without authentication, it poses a moderate risk. However, it does not directly enable code execution or denial of service, which limits its severity. The plugin is commonly used in WordPress environments to create popups, often on marketing or e-commerce sites, making it a relevant target for attackers seeking to gather intelligence on system configurations or user data.

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive system information, which may include configuration details, server paths, or other embedded data within the plugin. Such information leakage can aid attackers in crafting more effective attacks, including targeted exploits, phishing campaigns, or lateral movement within networks. Organizations relying on WordPress sites for customer engagement, e-commerce, or public services could face reputational damage if attackers leverage this information to compromise their systems. The impact is particularly significant for sectors handling sensitive personal data or financial transactions, as attackers could use the disclosed information to bypass security controls or identify further vulnerabilities. Although no active exploitation is currently known, the potential for reconnaissance makes this a risk that should be addressed promptly. Additionally, the exposure could violate data protection regulations such as GDPR if personal or sensitive data is indirectly exposed or if the vulnerability leads to a broader compromise.

1. Monitor ThemeHunk’s official channels and security advisories for a patch addressing CVE-2025-62902 and apply updates immediately upon release. 2. Until a patch is available, restrict access to the WP Popup Builder plugin’s endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting plugin-specific URLs or parameters. 3. Conduct a thorough audit of WordPress installations to identify all instances of the WP Popup Builder plugin and verify their versions. 4. Limit administrative and plugin management privileges to trusted personnel only, reducing the risk of exploitation through compromised accounts. 5. Employ security plugins or tools that can detect unusual access patterns or attempts to retrieve sensitive data from plugins. 6. Review and harden WordPress configuration, including disabling directory listing and ensuring that sensitive files are not publicly accessible. 7. Educate site administrators about the risks of outdated plugins and the importance of timely updates. 8. Consider isolating critical WordPress environments or using containerization to limit the blast radius of potential exploits.
