CVE-2025-14165 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Kirim.Email WooCommerce Integration plugin for WordPress, affecting all versions up to and including 1.2.9. The root cause is the absence of nonce validation on the plugin's settings page, which is a critical security mechanism designed to verify that requests made to change settings originate from legitimate users and not from malicious third-party sites. Without this protection, an attacker can craft a malicious web request that, when executed by an authenticated administrator (e.g., by clicking a link), modifies the plugin's API credentials and integration settings without the administrator's consent. This vulnerability requires user interaction but no prior authentication, as the attacker exploits the administrator's active session. The impact primarily concerns the integrity of the plugin's configuration, potentially allowing attackers to redirect email communications, disrupt integration functionality, or facilitate further attacks such as phishing or data interception. The CVSS v3.1 score is 4.3 (medium severity), reflecting the network attack vector, low complexity, no privileges required, but requiring user interaction and limited impact on integrity only. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly to prevent exploitation.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the Kirim.Email integration, this vulnerability poses a risk of unauthorized modification of email integration settings. This could lead to misdirected transactional emails, loss of customer trust, or enable attackers to insert malicious content into communications. While the vulnerability does not directly compromise data confidentiality or availability, the integrity compromise can facilitate phishing campaigns or fraud, impacting brand reputation and customer relationships. Organizations with high reliance on email-based workflows or automated communications are particularly vulnerable. The risk is heightened in sectors with stringent data protection regulations like GDPR, where unauthorized changes could lead to compliance issues. Additionally, attackers could leverage this vulnerability as a foothold for broader attacks within the affected WordPress environment.

1. Monitor for and apply official plugin updates from developerke that address nonce validation on the settings page as soon as they are released. 2. Until patches are available, restrict administrative access to trusted personnel only and limit exposure of the WordPress admin interface via IP whitelisting or VPN access. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious POST requests targeting the plugin’s settings endpoints. 4. Educate site administrators about the risks of clicking unsolicited links, especially when logged into administrative accounts. 5. Regularly audit plugin configurations and API credentials for unauthorized changes. 6. Consider disabling or replacing the Kirim.Email WooCommerce Integration plugin if immediate patching is not feasible, to reduce attack surface. 7. Employ security plugins that enforce nonce validation or add additional CSRF protections as a temporary measure.
