CVE-2025-52783 is a high-severity vulnerability classified as CWE-352, indicating a Cross-Site Request Forgery (CSRF) issue in the themelocation 'Change Cart button Colors WooCommerce' plugin. This vulnerability allows an attacker to perform unauthorized actions on behalf of an authenticated user without their consent. Specifically, the CSRF flaw enables Stored Cross-Site Scripting (XSS) attacks, where malicious scripts can be injected and persist within the application. The affected product is a WooCommerce plugin that customizes the appearance of the cart button colors, with versions up to 1.0 being vulnerable. The CVSS v3.1 base score is 7.1, reflecting a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact metrics indicate low confidentiality (C:L), integrity (I:L), and availability (A:L) impacts individually, but combined they represent a significant risk. The vulnerability was published on June 20, 2025, and no known exploits are currently reported in the wild. No patches or fixes have been linked yet, indicating that mitigation may require manual intervention or vendor updates. The vulnerability arises because the plugin does not properly validate or protect state-changing requests against CSRF attacks, allowing attackers to craft malicious web pages that, when visited by authenticated WooCommerce users, execute unauthorized actions and inject persistent malicious scripts. This can lead to session hijacking, data manipulation, or further compromise of the affected e-commerce sites.

For European organizations using WooCommerce with the themelocation 'Change Cart button Colors' plugin, this vulnerability poses a significant risk to e-commerce platforms. The Stored XSS enabled by CSRF can lead to theft of user credentials, session tokens, or manipulation of shopping cart data, potentially resulting in financial fraud or reputational damage. The integrity of transaction data can be compromised, undermining customer trust and regulatory compliance, especially under GDPR where data protection is critical. Availability impacts are limited but could occur if injected scripts disrupt normal site operations. Since WooCommerce is widely used by small to medium-sized enterprises (SMEs) across Europe for online retail, the threat can affect a broad range of sectors including retail, hospitality, and services. Attackers exploiting this vulnerability could target customers or administrators, leading to unauthorized purchases, data leakage, or site defacement. The requirement for user interaction (UI:R) means phishing or social engineering could be used to lure users to malicious sites, increasing the attack surface. The lack of known exploits currently provides a window for proactive defense, but the high CVSS score and scope change indicate that once exploited, the impact could extend beyond the plugin to the entire e-commerce environment.

1. Immediate mitigation should include disabling or uninstalling the vulnerable 'Change Cart button Colors WooCommerce' plugin until a vendor patch is released. 2. Implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns and suspicious POST requests targeting the plugin's endpoints. 3. Enforce strict Content Security Policy (CSP) headers to limit the execution of injected scripts and reduce the impact of Stored XSS. 4. Educate users and administrators about phishing risks and encourage cautious behavior when clicking on links, especially from untrusted sources. 5. Review and harden WooCommerce and WordPress security configurations, including enabling nonce verification for all state-changing requests to prevent CSRF. 6. Monitor logs for unusual activities such as unexpected cart modifications or script injections. 7. Once available, promptly apply official patches or updates from themelocation. 8. Conduct regular security assessments and penetration testing focusing on CSRF and XSS vectors within the e-commerce environment. 9. Consider implementing multi-factor authentication (MFA) for administrative access to reduce the risk of session hijacking.
