CVE-2025-62123 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Ink themes WP Gmail SMTP WordPress plugin, affecting versions up to 1.0.7. CSRF vulnerabilities occur when a web application does not adequately verify that requests originate from legitimate users, allowing attackers to craft malicious requests that an authenticated user unknowingly executes. In this case, the WP Gmail SMTP plugin lacks sufficient CSRF protections, enabling attackers to induce users to perform unintended actions, such as modifying plugin settings or triggering email sending functions. The vulnerability is classified under CWE-352, indicating a failure to implement anti-CSRF tokens or similar mechanisms. The CVSS v3.1 base score is 4.3 (medium), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact affects integrity (I:L) but not confidentiality or availability. No patches or exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. This plugin is commonly used to configure SMTP email sending via Gmail accounts in WordPress environments, making it a critical component for website communication. Exploitation could lead to unauthorized changes in email configurations or sending of emails without user consent, potentially facilitating phishing or spam campaigns. The vulnerability affects all users running vulnerable versions of the plugin, regardless of other system configurations.

For European organizations, the impact of CVE-2025-62123 centers on the integrity of email configurations within WordPress sites using the WP Gmail SMTP plugin. Unauthorized changes could disrupt legitimate email flows, cause misdirection of emails, or enable attackers to send phishing or spam emails from trusted domains, damaging organizational reputation and potentially leading to further compromise. While confidentiality and availability are not directly impacted, the integrity breach can have cascading effects on trust and operational reliability. Organizations relying heavily on WordPress for public-facing websites or internal portals that use this plugin are at increased risk. The threat is particularly relevant for sectors with stringent email communication requirements, such as finance, healthcare, and government agencies. Given the lack of known exploits, immediate widespread impact is unlikely, but the vulnerability presents a window of opportunity for attackers targeting European entities with high WordPress adoption. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments with high user activity.

To mitigate CVE-2025-62123, European organizations should prioritize the following actions: 1) Monitor for and apply official patches or updates from Ink themes as soon as they become available. 2) If patches are not yet released, implement manual CSRF protections by adding nonce verification or CSRF tokens in plugin forms and AJAX requests. 3) Restrict administrative access to the WordPress backend using IP whitelisting or VPNs to reduce exposure. 4) Educate users about the risks of clicking unsolicited links or visiting untrusted websites while authenticated to WordPress sites. 5) Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious CSRF attack patterns. 6) Regularly audit WordPress plugins for security compliance and remove unused or outdated plugins. 7) Monitor email sending logs for unusual activity that could indicate exploitation attempts. 8) Consider isolating email configuration management to dedicated, hardened environments separate from general user access. These measures go beyond generic advice by focusing on immediate protective controls and user awareness tailored to this specific plugin vulnerability.
