CVE-2024-6584 is a critical Server-Side Request Forgery (SSRF) vulnerability identified in the WordPress plugin Jetpack Boost. The vulnerability arises from the 'wp_ajax_boost_proxy_ig' AJAX action, which allows authenticated administrators to make arbitrary GET requests to any URL. SSRF vulnerabilities enable attackers to abuse a vulnerable server to send crafted requests to internal or external systems, potentially bypassing firewall restrictions and accessing sensitive internal resources. In this case, the vulnerability does not require user interaction beyond administrator privileges, and the CVSS score of 9.1 indicates a high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability impacts confidentiality and integrity, as attackers can leverage the SSRF to access internal services, exfiltrate data, or perform further attacks such as scanning internal networks or exploiting other vulnerabilities. Although no known exploits are currently reported in the wild, the critical severity and ease of exploitation make this a significant risk. The affected product is Jetpack Boost, a WordPress plugin designed to improve website performance, but the exact affected versions are unspecified (noted as '0'). The vulnerability was published on May 15, 2025, and is tracked under CWE-918 (SSRF). No patches or fixes are currently linked, indicating that mitigation may require vendor action or temporary workarounds.

For European organizations, this SSRF vulnerability poses a serious threat, especially for those relying on WordPress sites with Jetpack Boost installed. The ability for an attacker to make arbitrary requests from the server can lead to unauthorized access to internal systems, including databases, intranet services, or cloud metadata endpoints, potentially exposing sensitive business data or credentials. This can result in data breaches, intellectual property theft, or lateral movement within the network. Given the critical CVSS score and the fact that no user interaction is required, attackers could automate exploitation if they gain administrator access or if the vulnerability can be chained with other flaws to escalate privileges. The impact is heightened for organizations in regulated sectors such as finance, healthcare, and government within Europe, where data protection laws like GDPR impose strict requirements on data confidentiality and breach notification. Additionally, the integrity of website content and services could be compromised, damaging reputation and trust. The lack of a patch increases the urgency for organizations to implement interim mitigations to reduce exposure.

1. Immediate mitigation should focus on restricting access to the 'wp_ajax_boost_proxy_ig' AJAX action by limiting administrator privileges strictly to trusted personnel and auditing administrator accounts for suspicious activity. 2. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious SSRF patterns or unusual outbound requests originating from the WordPress server. 3. Network segmentation should be enforced to isolate the WordPress server from sensitive internal resources, minimizing the impact of SSRF exploitation. 4. Monitor outbound traffic from the WordPress server for anomalous requests to internal IP ranges or unexpected external destinations. 5. Disable or remove the Jetpack Boost plugin if it is not essential, or temporarily deactivate the vulnerable functionality until a vendor patch is released. 6. Keep WordPress core and all plugins updated and subscribe to vendor security advisories for timely patching once available. 7. Conduct thorough security audits and penetration testing focusing on SSRF and related vulnerabilities to identify and remediate similar issues.
