CVE-2025-66129 identifies a Missing Authorization vulnerability in the wppochipp Pochipp plugin, a WordPress plugin used for e-commerce or content management functionalities. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to bypass authorization checks. This means that certain actions or data that should be restricted to authenticated or privileged users may be accessible to unauthenticated or lower-privileged attackers. The affected versions include all versions up to and including 1.18.0, with no specific earliest affected version indicated. The vulnerability was reserved in November 2025 and published in December 2025, but no CVSS score has been assigned yet, and no public exploits are known at this time. The lack of authorization checks typically leads to privilege escalation or unauthorized data access, which can compromise confidentiality and integrity of the affected systems. Since Pochipp is a plugin integrated into WordPress environments, exploitation could impact websites relying on it for critical business functions. The vulnerability does not specify whether user interaction is required, but missing authorization generally implies that an attacker can exploit it remotely without authentication or with minimal privileges. The absence of patch links suggests that fixes may not yet be publicly available, emphasizing the need for vigilance and proactive security measures.

For European organizations, the impact of CVE-2025-66129 could be significant, especially for those using the Pochipp plugin in their WordPress environments to manage e-commerce or other sensitive operations. Unauthorized access could lead to data leakage, unauthorized transactions, or manipulation of website content, undermining customer trust and regulatory compliance such as GDPR. The confidentiality of customer data and business information could be compromised, and integrity of transactions or content could be affected. Availability impact is less clear but could occur if attackers modify or disrupt plugin functionality. Given the widespread use of WordPress and its plugins across Europe, organizations in sectors like retail, finance, and media are particularly at risk. The vulnerability could also facilitate further attacks, such as lateral movement or installation of malware, if exploited successfully. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability details become widely known.

Organizations should immediately inventory their WordPress installations to identify the use of the Pochipp plugin and its version. Until an official patch is released, restrict access to administrative interfaces and sensitive plugin endpoints through network segmentation, IP whitelisting, or web application firewalls (WAFs) with custom rules to block suspicious requests. Conduct thorough access control reviews to ensure that no unauthorized users have elevated privileges. Monitor logs for unusual access patterns or attempts to exploit authorization weaknesses. Engage with the vendor or security community for updates on patches or workarounds. Consider disabling or removing the plugin if it is not essential to reduce attack surface. Implement multi-factor authentication (MFA) for all administrative accounts to limit the impact of potential unauthorized access. Prepare incident response plans to quickly address any exploitation attempts. Finally, educate website administrators about the risks and signs of exploitation related to this vulnerability.
