CVE-2025-62998 is classified under CWE-201, which involves the insertion of sensitive information into sent data, leading to unintended data exposure. The vulnerability exists in the WP Messiah WP AI CoPilot WordPress plugin, versions up to 1.2.7. It allows an attacker with low privileges (PR:L) to retrieve embedded sensitive data that the plugin sends externally, without requiring user interaction (UI:N). The attack vector is network-based (AV:N), meaning exploitation can occur remotely. The vulnerability does not affect data integrity or availability but compromises confidentiality by exposing sensitive information embedded in outgoing data streams. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the attacker’s initial privileges, potentially impacting other users or systems. No patches have been published yet, and no known exploits are reported in the wild. The issue likely stems from inadequate sanitization or encryption of sensitive data before transmission, allowing attackers to intercept or access this data. Since WP AI CoPilot is an AI assistant plugin, it may handle user inputs, content, or configuration data that could be sensitive. The vulnerability’s medium severity reflects the moderate impact on confidentiality and the requirement for some privilege level to exploit it.

For European organizations, this vulnerability poses a risk of sensitive data leakage from WordPress sites using the WP AI CoPilot plugin. Organizations handling personal data, intellectual property, or regulated information (e.g., GDPR-protected data) could face compliance and reputational risks if sensitive information is exposed. Although the vulnerability does not allow modification or disruption of services, the confidentiality breach could lead to further targeted attacks or data misuse. The remote exploitability and lack of user interaction increase the risk of automated or stealthy data exfiltration. Given the widespread use of WordPress in Europe, especially among SMEs and content-driven businesses, the vulnerability could affect a broad range of sectors including finance, healthcare, legal, and media. The absence of known exploits currently provides a window for proactive mitigation, but organizations should act promptly to prevent potential future exploitation.

1. Immediately audit all WordPress installations for the presence of WP Messiah WP AI CoPilot plugin and identify versions up to 1.2.7. 2. Restrict plugin usage to trusted administrators and limit privileges to the minimum necessary to reduce exploitation risk. 3. Monitor outgoing network traffic from WordPress servers for unusual data transmissions that could indicate sensitive data leakage. 4. Disable or remove the WP AI CoPilot plugin if it is not essential, especially in environments processing sensitive data. 5. Implement network-level controls such as web application firewalls (WAFs) to detect and block suspicious requests targeting the plugin. 6. Stay alert for official patches or updates from WP Messiah and apply them promptly once available. 7. Educate site administrators about the risks of sensitive data exposure through plugins and enforce strict data handling policies. 8. Consider isolating WordPress environments or using containerization to limit lateral movement in case of compromise. 9. Conduct regular vulnerability scans and penetration tests focusing on plugin security and data leakage vectors.
