CVE-2025-58977 is a Server-Side Request Forgery (SSRF) vulnerability identified in the WordPress plugin 'WP eBay Product Feeds' developed by Rhys Wynne. This vulnerability affects versions up to 3.4.8 of the plugin. SSRF vulnerabilities occur when an attacker can manipulate a server-side application to make HTTP requests to arbitrary domains or IP addresses, potentially allowing the attacker to access internal systems, bypass firewalls, or interact with otherwise inaccessible services. In this case, the vulnerability allows an attacker to craft requests that the plugin will execute on the server side, potentially leading to unauthorized information disclosure or internal network reconnaissance. The CVSS v3.1 base score is 4.9, indicating a medium severity level. The vector string (AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N) shows that the attack can be launched remotely over the network, requires low privileges, no user interaction, but has a high attack complexity and impacts confidentiality and integrity with a scope change. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is classified under CWE-918, which specifically relates to SSRF issues. Given the plugin's role in integrating eBay product feeds into WordPress sites, the SSRF flaw could be exploited to access internal resources or sensitive data that the server can reach but external attackers cannot. This could lead to further attacks or data leakage depending on the internal network configuration and the privileges of the WordPress server.

For European organizations using WordPress sites with the WP eBay Product Feeds plugin, this SSRF vulnerability poses a risk of unauthorized internal network access and data exposure. Attackers could leverage the vulnerability to scan internal IP ranges, access metadata services (especially in cloud environments), or interact with internal APIs that are not exposed externally. This could lead to the disclosure of sensitive information such as internal configuration data, credentials, or other protected resources. Although the CVSS score is medium, the scope change indicates that the vulnerability could affect systems beyond the initial WordPress server, potentially impacting confidentiality and integrity of internal systems. European organizations with sensitive internal networks or those operating in regulated sectors (finance, healthcare, government) could face compliance risks if internal data is exposed. Additionally, the lack of user interaction and remote exploitability means attackers can automate attacks at scale. The absence of known exploits currently reduces immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation. The impact on availability is low, so denial of service is unlikely, but the confidentiality and integrity risks warrant attention.

1. Immediate mitigation should include updating the WP eBay Product Feeds plugin to a patched version once it becomes available. Monitor official sources for patch releases. 2. Until a patch is released, restrict outbound HTTP requests from the WordPress server to only trusted domains using firewall rules or web application firewall (WAF) policies to limit SSRF exploitation. 3. Implement network segmentation to isolate the WordPress server from sensitive internal services and metadata endpoints, reducing the attack surface. 4. Use security plugins or custom code to validate and sanitize all inputs that could influence server-side requests, ensuring only legitimate URLs are processed. 5. Monitor logs for unusual outbound requests originating from the WordPress server that could indicate SSRF exploitation attempts. 6. Employ an intrusion detection system (IDS) or endpoint detection and response (EDR) solutions to detect anomalous network activity. 7. Review and minimize the privileges of the WordPress server user to limit the potential impact of exploitation. 8. Educate administrators on the risks of SSRF and ensure timely application of security updates for all WordPress plugins.
