CVE-2025-62998 identifies a vulnerability classified under CWE-201 (Insertion of Sensitive Information Into Sent Data) in the WP Messiah WP AI CoPilot plugin for WordPress. This vulnerability allows an attacker with network access and low privileges to retrieve sensitive information embedded improperly into data sent by the plugin. The issue stems from the plugin's failure to adequately sanitize or segregate sensitive data before transmission, potentially exposing confidential information to unauthorized parties. The vulnerability affects all versions up to 1.2.7, with no patches currently available at the time of reporting. The CVSS v3.1 base score is 5.0, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and a confidentiality impact (C:L) but no integrity or availability impact. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. No known exploits have been reported in the wild, but the vulnerability poses a risk of sensitive data leakage, which could include user credentials, API keys, or other confidential information handled by the plugin. The vulnerability's exploitation does not require user interaction, increasing the risk profile. The plugin is used to enhance WordPress sites with AI capabilities, implying that sensitive data processed by the AI features could be exposed. The lack of patches necessitates immediate attention to monitoring and mitigation strategies.

For European organizations, the primary impact of CVE-2025-62998 is the potential unauthorized disclosure of sensitive information processed or transmitted by the WP AI CoPilot plugin. This could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Organizations relying on WordPress sites with AI-enhanced features may inadvertently expose confidential business data or customer information. The confidentiality impact could facilitate further attacks, such as phishing or lateral movement within networks. Since the vulnerability does not affect integrity or availability, direct disruption of services is unlikely. However, the exposure of sensitive data can undermine trust and compliance obligations. The requirement for low privileges and network access means internal threat actors or attackers who have gained limited access could exploit this vulnerability. European entities in sectors like finance, healthcare, and e-commerce, which often use WordPress for customer-facing portals, are particularly at risk. The absence of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

1. Monitor WP Messiah communications for official patches or updates addressing CVE-2025-62998 and apply them promptly once released. 2. Until patches are available, restrict network access to the WordPress environment hosting WP AI CoPilot, limiting exposure to trusted IP ranges and internal networks only. 3. Conduct a thorough audit of the plugin’s data handling and transmission processes to identify and isolate sensitive information flows. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious traffic patterns targeting the plugin endpoints. 5. Review and minimize the privileges assigned to the plugin and associated user roles within WordPress to reduce exploitation potential. 6. Employ data encryption in transit (e.g., enforce HTTPS/TLS) to protect data sent by the plugin from interception. 7. Educate administrators and developers about the vulnerability to avoid inadvertent exposure through configuration or customizations. 8. Consider temporary disabling or replacing the WP AI CoPilot plugin if sensitive data exposure risk is unacceptable and no patch is available. 9. Maintain comprehensive logging and monitoring to detect any anomalous access or data exfiltration attempts related to the plugin.
