CVE-2025-62890 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Premmerce Brands for WooCommerce plugin, versions up to and including 1.2.13. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to perform unwanted actions on a web application without their knowledge. In this case, the vulnerability exists because the plugin does not adequately verify that requests modifying settings or data originate from legitimate sources, such as through missing or ineffective anti-CSRF tokens. An attacker can craft a malicious webpage or email containing a request that, when visited or clicked by an authenticated WooCommerce administrator, executes privileged actions like changing brand settings or manipulating product data. This can compromise the integrity of the e-commerce platform, potentially leading to unauthorized data changes or disruptions in service. The vulnerability affects WooCommerce installations using the Premmerce Brands plugin, a popular extension for managing product brands. Although no public exploits have been reported, the lack of authentication barriers and the administrative level of impact make this a significant risk. The vulnerability was published on October 27, 2025, with no CVSS score assigned yet, and no patches currently linked, indicating that remediation may still be pending or in progress.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the Premmerce Brands plugin, this vulnerability poses a risk of unauthorized administrative actions. Such actions could include altering product brand information, disrupting catalog integrity, or potentially affecting order processing workflows. This can lead to loss of customer trust, financial losses, and reputational damage. The impact on confidentiality is limited as the vulnerability primarily affects integrity and availability. However, unauthorized changes could indirectly expose sensitive business information or disrupt operations. Given the widespread use of WooCommerce in Europe, particularly in countries with mature e-commerce markets, the threat could affect a broad range of small to medium-sized enterprises. The absence of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks, especially from threat actors aiming to disrupt commercial activities or conduct fraud.

Organizations should monitor for official patches or updates from Premmerce and apply them promptly once available. In the interim, administrators should implement strict access controls, limiting administrative privileges to trusted personnel and using multi-factor authentication to reduce the risk of session hijacking. Web application firewalls (WAFs) can be configured to detect and block suspicious cross-site requests. Additionally, site owners should verify that anti-CSRF tokens are properly implemented in all forms and requests that modify data. Regular security audits and monitoring for unusual administrative activity can help detect exploitation attempts early. Educating administrators about the risks of clicking unknown links while logged into administrative accounts can further reduce exposure. If possible, temporarily disabling or restricting the Premmerce Brands plugin until a patch is available may be warranted for high-risk environments.
