CVE-2025-62902 is a vulnerability identified in the ThemeHunk WP Popup Builder WordPress plugin, specifically in versions up to and including 1.3.6. The flaw allows an attacker with no privileges and without any user interaction to remotely access sensitive system information embedded within the plugin or its environment. This exposure occurs due to insufficient access control mechanisms protecting sensitive data endpoints or embedded information within the plugin's code or configuration. The vulnerability is classified under the category of information disclosure, impacting confidentiality but not integrity or availability. The CVSS v3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact. Although no exploits are currently known in the wild, the vulnerability poses a significant risk because it can be exploited remotely and silently, potentially leaking sensitive information such as configuration details, system paths, or other embedded secrets that could facilitate further attacks. The vulnerability was published on October 27, 2025, and assigned by Patchstack. The lack of an official patch link suggests that remediation may still be pending or requires manual intervention. Organizations using this plugin should consider the risk of sensitive data exposure and take immediate steps to mitigate it.

For European organizations, the exposure of sensitive system information can lead to increased risk of targeted attacks, including credential theft, privilege escalation, or lateral movement within networks. Confidential data leakage may include server paths, database credentials, API keys, or other configuration details that attackers can leverage to compromise the broader IT environment. This is particularly critical for organizations operating public-facing websites with sensitive customer data or proprietary business information. The vulnerability's remote and unauthenticated nature means attackers can exploit it without needing access credentials or user interaction, increasing the likelihood of automated scanning and exploitation attempts. Industries such as e-commerce, media, finance, and government entities in Europe that rely on WordPress and this plugin for marketing or customer engagement are at heightened risk. The impact is primarily on confidentiality, but the resulting information disclosure can facilitate subsequent attacks that may affect integrity and availability indirectly.

1. Monitor ThemeHunk’s official channels for an official patch or update addressing CVE-2025-62902 and apply it immediately upon release. 2. Until a patch is available, restrict access to the plugin’s files and endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting known vulnerable paths or parameters. 3. Conduct a manual code review of the plugin to identify and remove or obfuscate any embedded sensitive information that is unnecessarily exposed. 4. Limit the exposure of the WordPress installation by enforcing strict file permissions and disabling directory listing on the web server. 5. Employ network segmentation and intrusion detection systems to monitor for unusual access patterns or data exfiltration attempts related to the plugin. 6. Educate site administrators on the risks of using outdated or unpatched plugins and encourage regular vulnerability scanning and plugin inventory management. 7. Consider temporary deactivation or replacement of the WP Popup Builder plugin with a more secure alternative if immediate patching is not feasible.
