CVE-2025-64290 is a Cross-Site Request Forgery (CSRF) vulnerability found in the Premmerce Product Search plugin for WooCommerce, specifically affecting versions up to and including 2.2.4. CSRF vulnerabilities occur when a web application does not properly verify that requests made to it originate from an authenticated and intended user, allowing attackers to craft malicious web pages or links that cause victims to unknowingly perform actions on the vulnerable site. In this case, the Premmerce plugin fails to implement adequate CSRF protections on certain actions, enabling attackers to induce authenticated WooCommerce administrators or users to execute unwanted requests. The vulnerability has a CVSS 3.1 base score of 4.3, reflecting a medium severity level. The vector indicates that the attack can be performed remotely (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to confidentiality (C:L), with no impact on integrity or availability. This suggests that sensitive information could be exposed or leaked, but the attacker cannot modify data or disrupt service. No known exploits have been reported in the wild, and no patches or updates are currently linked, indicating that remediation may be pending or that users should monitor vendor advisories. The vulnerability affects WooCommerce sites using the Premmerce Product Search plugin, a popular e-commerce search enhancement tool, which is widely used in online retail environments.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the Premmerce Product Search plugin, this vulnerability poses a risk of unauthorized actions triggered via social engineering or malicious web content. While the direct impact is limited to confidentiality, attackers could potentially extract sensitive information or perform actions that reveal internal data. This could lead to privacy violations, customer trust erosion, or compliance issues under regulations such as GDPR. The lack of impact on integrity and availability reduces the risk of data tampering or service disruption, but the exposure of confidential information remains a concern. Organizations with large online retail operations or those handling sensitive customer data are at higher risk. The medium severity rating suggests that while the threat is not critical, it should not be ignored, especially given the ease of exploitation and the common use of WooCommerce in Europe.

To mitigate this vulnerability, European organizations should first verify if they are using Premmerce Product Search for WooCommerce versions up to 2.2.4 and plan to update to a patched version once available. In the absence of an immediate patch, implementing web application firewall (WAF) rules to detect and block CSRF attack patterns can reduce risk. Site administrators should ensure that anti-CSRF tokens are enabled and properly validated for all state-changing requests within the WooCommerce environment. Additionally, enforcing strict Content Security Policy (CSP) headers can help prevent malicious cross-origin requests. User education is critical; training staff and users to recognize phishing attempts and suspicious links can reduce the likelihood of successful exploitation. Monitoring logs for unusual activity related to the plugin's functions can provide early detection of attempted attacks. Finally, limiting administrative privileges and employing multi-factor authentication (MFA) can further reduce the impact of any successful CSRF attempts.
