CVE-2026-24606 identifies a Missing Authorization vulnerability in the Bayarcash WooCommerce plugin developed by Web Impian, affecting versions up to and including 4.3.11. The vulnerability arises from incorrectly configured access control security levels within the plugin, which is used to integrate Bayarcash payment services into WooCommerce-based e-commerce websites. Missing authorization means that certain functions or data that should be restricted to authorized users can be accessed or manipulated by unauthorized actors. This could allow attackers to perform unauthorized operations such as viewing sensitive information, manipulating payment processes, or altering order details without proper permissions. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no exploits have been reported in the wild yet, the plugin’s widespread use in e-commerce environments makes it a valuable target. The lack of a CVSS score indicates the need for a manual severity assessment based on the potential impact on confidentiality, integrity, and availability, as well as ease of exploitation and scope. The vulnerability primarily threatens the confidentiality and integrity of transaction data and user information, potentially leading to financial fraud or data breaches. The plugin’s role in payment processing amplifies the risk to business operations and customer trust. The absence of a patch link suggests that a fix may not yet be available, emphasizing the importance of interim mitigations and monitoring.

For European organizations, the impact of CVE-2026-24606 can be significant, especially for those operating e-commerce platforms using WooCommerce with the Bayarcash payment integration. Unauthorized access could lead to exposure of sensitive customer data, manipulation of payment transactions, and potential financial losses. This could also result in reputational damage and regulatory penalties under GDPR due to data breaches. The integrity of order and payment processing could be compromised, disrupting business operations and customer trust. Given the critical role of e-commerce in many European economies, particularly in countries with high digital commerce adoption, the vulnerability could affect a broad range of sectors including retail, finance, and services. The lack of known exploits currently provides a window for proactive defense, but the ease of exploitation due to missing authorization controls means attackers could develop exploits rapidly. Organizations may also face increased scrutiny from regulators if breaches occur, amplifying the operational and legal impact.

1. Immediately audit and restrict access permissions to the Bayarcash WooCommerce plugin settings and functionalities to trusted administrators only. 2. Monitor logs and user activity for unusual access patterns or unauthorized attempts to access restricted functions. 3. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 4. Engage with the vendor (Web Impian) and Patchstack for updates or patches and apply them promptly once available. 5. Consider temporarily disabling the Bayarcash WooCommerce plugin if feasible until a patch is released. 6. Conduct thorough security reviews of all WooCommerce plugins to identify similar authorization weaknesses. 7. Educate administrative users on the risks of unauthorized access and enforce strong authentication mechanisms such as MFA. 8. Regularly back up e-commerce data and configurations to enable rapid recovery in case of compromise. 9. Use vulnerability scanning tools tailored to WordPress and WooCommerce environments to detect this and related vulnerabilities. 10. Collaborate with incident response teams to prepare for potential exploitation scenarios and ensure rapid containment.
