CVE-2025-47633 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Awin – Advertiser Tracking plugin for WooCommerce, a popular e-commerce platform plugin used to integrate affiliate tracking capabilities. This vulnerability affects versions up to 2.0.0 of the plugin. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a request that performs an unwanted action on a web application in which the user is currently authenticated. In this case, the vulnerability allows an attacker to craft malicious requests that, when executed by a logged-in WooCommerce administrator or user with sufficient privileges, could alter tracking configurations or advertiser data without the user’s consent. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires no privileges, but does require user interaction (the user must be authenticated and perform an action such as clicking a link). The impact is limited to integrity (I:L) with no confidentiality or availability impact. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is classified under CWE-352, which is a common web security weakness related to CSRF attacks. Since WooCommerce is widely used in e-commerce websites, this vulnerability could be exploited to manipulate affiliate tracking data, potentially leading to fraudulent commission payments or disruption of affiliate marketing analytics.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the Awin Advertiser Tracking plugin, this vulnerability poses a risk to the integrity of affiliate tracking data. Attackers could manipulate tracking parameters or advertiser settings, potentially causing financial losses through fraudulent affiliate commissions or misattribution of sales. This could also damage trust with affiliate partners and customers. While the vulnerability does not directly expose sensitive data or cause service outages, the integrity compromise can have significant business impacts. Given the widespread adoption of WooCommerce in Europe, particularly among small to medium enterprises in countries with strong e-commerce sectors such as Germany, the UK, France, and the Netherlands, the threat is relevant. Additionally, organizations in regulated sectors with strict data integrity requirements could face compliance risks if affiliate data is tampered with. The requirement for user interaction and authentication limits the attack surface but does not eliminate risk, especially if phishing or social engineering tactics are employed to trick administrators into executing malicious requests.

To mitigate this vulnerability, European organizations should first verify if they are using the affected versions of the Awin – Advertiser Tracking for WooCommerce plugin. Immediate steps include: 1) Restrict administrative access to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of compromised accounts being used in CSRF attacks. 2) Implement web application firewalls (WAFs) that can detect and block suspicious CSRF attack patterns or anomalous requests targeting the plugin endpoints. 3) Educate administrators and users with elevated privileges about phishing and social engineering risks to prevent inadvertent execution of malicious requests. 4) Monitor affiliate tracking data and configuration changes closely for anomalies that could indicate exploitation attempts. 5) Follow vendor communications closely and apply patches or updates as soon as they become available. 6) If possible, implement anti-CSRF tokens or nonce validation in the plugin’s forms and API endpoints to prevent unauthorized requests. If the plugin does not currently support this, consider custom hardening or alternative affiliate tracking solutions with better security controls until a patch is released.
