CVE-2025-62890 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Premmerce Brands for WooCommerce plugin, specifically affecting versions up to and including 1.2.13. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request unknowingly, leveraging the user's active session and privileges. In this case, the vulnerability allows an attacker to perform unauthorized actions on the WooCommerce administrative interface without requiring any privileges or prior authentication, only relying on the victim’s authenticated session. The CVSS v3.1 score of 8.8 reflects a high severity due to the vulnerability's network attack vector, low complexity, no privileges required, but requiring user interaction (the victim must visit a malicious site). The impact covers confidentiality, integrity, and availability, meaning attackers could manipulate brand data, alter e-commerce configurations, or disrupt service availability. Although no exploits are currently known in the wild, the plugin’s widespread use in WooCommerce stores makes this a critical concern. The vulnerability arises from insufficient or missing anti-CSRF protections in the plugin’s request handling, allowing forged requests to be accepted and executed by the server. This can lead to unauthorized changes in product branding information or other administrative settings, potentially damaging business operations and customer trust.

For European organizations, this vulnerability poses a significant risk to e-commerce platforms relying on WooCommerce with the Premmerce Brands plugin. Successful exploitation could lead to unauthorized modification or deletion of brand-related data, impacting product presentation and customer experience. It could also enable attackers to inject malicious content or disrupt service availability, leading to financial losses and reputational damage. Given the high adoption of WooCommerce in Europe, especially in countries with strong e-commerce sectors like Germany, the UK, France, and the Netherlands, the potential impact is substantial. Additionally, compromised e-commerce platforms could be leveraged for further attacks such as data theft, fraud, or supply chain attacks. The vulnerability’s ease of exploitation and high impact on confidentiality, integrity, and availability make it a critical threat to business continuity and compliance with data protection regulations such as GDPR.

1. Immediate application of any available patches or updates from Premmerce addressing this vulnerability is the primary mitigation step. 2. If patches are not yet available, implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the plugin’s endpoints. 3. Enforce strict anti-CSRF tokens in all administrative forms and AJAX requests related to the Premmerce Brands plugin to ensure requests are legitimate. 4. Restrict administrative access to the WooCommerce backend by IP whitelisting or VPN access to reduce exposure. 5. Enable multi-factor authentication (MFA) for all administrative accounts to mitigate risks from session hijacking or social engineering. 6. Conduct regular monitoring and auditing of administrative actions and logs to detect unusual or unauthorized changes promptly. 7. Educate administrators about the risks of CSRF and advise against clicking on suspicious links while logged into the WooCommerce admin panel. 8. Consider isolating the WooCommerce admin interface behind additional authentication layers or reverse proxies to add defense-in-depth.
