CVE-2025-58203 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Solace Extra plugin developed by solacewp. SSRF vulnerabilities occur when an attacker can abuse a server functionality to make HTTP requests to arbitrary domains or internal systems, potentially bypassing network access controls. This vulnerability affects versions of Solace Extra up to and including 1.3.2. The CVSS 3.1 base score is 4.4, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N) shows that the attack requires network access, high attack complexity, and privileges (PR:H) on the system, with no user interaction needed. The impact includes limited confidentiality and integrity loss but no availability impact. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. Since no known exploits are currently reported in the wild and no patches have been linked yet, this vulnerability represents a moderate risk primarily to environments where Solace Extra is deployed and accessed by privileged users. The SSRF could allow an attacker to make unauthorized requests from the server to internal or external resources, potentially exposing sensitive information or enabling further attacks within the network.

For European organizations using the Solace Extra plugin, this SSRF vulnerability could lead to unauthorized internal network scanning or data exfiltration if an attacker gains privileged access to the system hosting the plugin. Although the attack requires high privileges, exploitation could facilitate lateral movement or reconnaissance within corporate networks, especially in environments with sensitive internal services not exposed externally. Confidentiality and integrity impacts are limited but could be significant if internal services contain sensitive data or critical business logic. The vulnerability does not directly impact availability, but indirect effects could arise from subsequent attacks leveraging SSRF. European organizations in sectors such as finance, healthcare, and government, which often deploy WordPress plugins like Solace Extra for content management or service integration, may face increased risk if internal network segmentation is weak or if privileged access controls are insufficient.

1. Restrict access to the Solace Extra plugin to only trusted and necessary privileged users to reduce the risk of exploitation. 2. Implement strict network segmentation and firewall rules to limit the server's ability to make outbound requests to sensitive internal resources. 3. Monitor and log outbound HTTP requests from servers running Solace Extra to detect unusual or unauthorized access patterns. 4. Apply the latest updates or patches from solacewp as soon as they become available to address this vulnerability. 5. Conduct regular security audits and penetration tests focusing on SSRF and related vulnerabilities in web-facing applications. 6. Employ Web Application Firewalls (WAFs) with rules designed to detect and block SSRF attack patterns targeting the Solace Extra plugin endpoints. 7. Educate system administrators and developers about the risks of SSRF and the importance of validating and sanitizing URLs or request parameters that the plugin processes.
