CVE-2025-6729: CWE-918 Server-Side Request Forgery (SSRF) in qazomardok PayMaster for WooCommerce
The PayMaster for WooCommerce plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 0.4.31 via the 'wp_ajax_paym_status' AJAX action This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
AI Analysis
Technical Summary
CVE-2025-6729 is a Server-Side Request Forgery (SSRF) vulnerability identified in the PayMaster for WooCommerce plugin for WordPress, specifically affecting all versions up to and including 0.4.31. The vulnerability resides in the 'wp_ajax_paym_status' AJAX action, which is accessible to authenticated users with Subscriber-level privileges or higher. SSRF vulnerabilities allow attackers to make arbitrary HTTP requests from the vulnerable server to internal or external systems. In this case, an attacker with minimal privileges can exploit the flaw to send crafted requests originating from the web application, potentially querying or modifying information on internal services that are otherwise inaccessible externally. This can lead to unauthorized data disclosure or manipulation within the internal network. The vulnerability has a CVSS v3.1 base score of 6.4, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires privileges (authenticated user with Subscriber role), does not require user interaction, and impacts confidentiality and integrity with a scope change. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-918, which covers SSRF issues where the server is tricked into making unintended requests. Given that WooCommerce is a widely used e-commerce plugin and PayMaster is a payment-related extension, the vulnerability could be leveraged to access sensitive internal services or payment infrastructure, potentially leading to data leakage or manipulation of payment status information.
Potential Impact
For European organizations using WordPress with the PayMaster for WooCommerce plugin, this SSRF vulnerability poses a significant risk to internal network security and data confidentiality. Exploitation could allow attackers to bypass network segmentation and access internal services such as databases, internal APIs, or cloud metadata services that are not exposed externally. This could lead to unauthorized disclosure of sensitive customer data, payment transaction details, or internal configuration information. The integrity impact means attackers might alter payment statuses or other critical data, potentially causing financial discrepancies or fraud. Although the vulnerability requires authenticated access at Subscriber level or above, many WordPress sites allow user registrations or have multiple users with such privileges, increasing the attack surface. The lack of known exploits in the wild suggests limited current exploitation, but the medium severity and scope change indicate a meaningful threat if weaponized. European e-commerce businesses, especially those handling payment processing via WooCommerce and PayMaster, must consider the risk of internal service compromise and potential regulatory implications under GDPR if customer data is exposed or altered.
Mitigation Recommendations
1. Immediate mitigation should include restricting or monitoring access to the 'wp_ajax_paym_status' AJAX action, especially limiting Subscriber-level user capabilities if possible. 2. Implement strict input validation and sanitization on all parameters processed by the AJAX handler to prevent SSRF payloads. 3. Employ network-level controls such as firewall rules or web application firewalls (WAFs) to block outbound requests from the web server to internal-only IP ranges or sensitive endpoints. 4. Monitor logs for unusual outbound HTTP requests originating from the WordPress server that could indicate SSRF attempts. 5. If feasible, isolate the WordPress server and payment processing components in segmented network zones to limit the impact of SSRF exploitation. 6. Stay updated with vendor advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Review user roles and permissions to minimize the number of users with Subscriber or higher privileges, and enforce strong authentication mechanisms. 8. Conduct internal penetration testing focusing on SSRF vectors to identify and remediate similar issues proactively.
