CVE-2025-47464 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Solace Extra plugin developed by solacewp, affecting versions up to and including 1.3.1. SSRF vulnerabilities occur when an attacker can manipulate a server to make unintended HTTP requests to internal or external resources, potentially bypassing network access controls. This specific vulnerability allows an attacker with low privileges (PR:L) and no user interaction (UI:N) to induce the server to send crafted requests to arbitrary destinations. The vulnerability has a CVSS v3.1 base score of 4.9, indicating a medium severity level. The attack vector is network-based (AV:N), but the attack complexity is high (AC:H), meaning exploitation requires some conditions or knowledge to succeed. The scope is changed (S:C), implying that the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. SSRF can be leveraged to access internal services, perform port scanning, or exploit other vulnerabilities within the internal network, potentially leading to further compromise. Given the nature of the plugin, which is likely used in WordPress environments, the vulnerability could be exploited to target internal infrastructure or cloud metadata services if accessible from the server hosting Solace Extra.

For European organizations using the Solace Extra plugin, this SSRF vulnerability poses a risk primarily to the confidentiality and integrity of internal network resources. Attackers could leverage this flaw to access sensitive internal services that are otherwise protected by network segmentation or firewalls. This could lead to unauthorized data disclosure or manipulation of internal systems. Although the vulnerability does not directly impact availability, the potential for lateral movement or pivoting within the network could facilitate more severe attacks. Organizations in Europe that rely on WordPress-based infrastructure with Solace Extra installed may face increased risk, especially if the plugin is used in environments with sensitive internal APIs or cloud metadata endpoints. The medium severity rating suggests that while the risk is not critical, it should not be ignored, particularly in sectors with stringent data protection requirements such as finance, healthcare, and government. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability details are public.

European organizations should prioritize the following mitigation steps: 1) Immediately audit all WordPress installations to identify the presence and version of the Solace Extra plugin. 2) If an updated patched version becomes available, apply it promptly. 3) In the absence of a patch, consider disabling or removing the Solace Extra plugin to eliminate the attack surface. 4) Implement network-level controls to restrict outbound HTTP requests from web servers hosting WordPress to only trusted destinations, thereby limiting SSRF exploitation potential. 5) Employ Web Application Firewalls (WAFs) with rules designed to detect and block SSRF attack patterns targeting the plugin. 6) Monitor logs for unusual outbound requests or internal service access attempts originating from the WordPress server. 7) Conduct internal penetration testing focusing on SSRF vectors to identify and remediate similar vulnerabilities. 8) Educate system administrators and security teams about SSRF risks and the importance of minimizing plugin usage to trusted and actively maintained components.
