CVE-2025-7813 is a Server-Side Request Forgery (SSRF) vulnerability classified under CWE-918, found in the Eventin – AI Powered Event Manager, Events Calendar, Booking and Tickets plugin for WordPress developed by arraytics. This vulnerability affects all versions up to and including 4.0.37. The issue resides in the proxy_image function, which improperly handles user-supplied input to make web requests. An unauthenticated attacker can exploit this flaw to cause the web application to send HTTP requests to arbitrary URLs, including internal network resources that are not directly accessible from the internet. This can lead to unauthorized information disclosure and potential modification of internal services, undermining confidentiality and integrity. The vulnerability does not require user interaction or authentication, making it easier to exploit remotely. The CVSS v3.1 base score is 7.2, with vector AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N, indicating network attack vector, low complexity, no privileges or user interaction needed, and a scope change due to impact on resources beyond the vulnerable component. Although no exploits have been reported in the wild yet, the nature of SSRF vulnerabilities makes them attractive for attackers to pivot into internal networks or cloud metadata services. The vulnerability was publicly disclosed on August 23, 2025, with no official patches available at the time of reporting.

The primary impact of CVE-2025-7813 is the potential for attackers to leverage the SSRF vulnerability to access internal network resources that are otherwise protected from external access. This can lead to unauthorized disclosure of sensitive information such as internal APIs, databases, or cloud metadata endpoints, which may contain credentials or configuration data. Attackers may also manipulate internal services if they accept HTTP requests, potentially altering data or disrupting operations. Since the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to organizations running the affected plugin on publicly accessible WordPress sites. The compromise of internal services can facilitate further lateral movement within an organization's infrastructure, increasing the risk of data breaches or service disruptions. The vulnerability's scope change means that the impact extends beyond the plugin itself to other systems within the internal network. Organizations relying on this plugin for event management and ticketing may face reputational damage, financial loss, and regulatory consequences if exploited.

1. Immediate mitigation should focus on updating the Eventin plugin to a version that addresses this vulnerability once available from the vendor. 2. Until a patch is released, disable or restrict the proxy_image functionality if possible, or remove the plugin if it is not critical. 3. Implement strict network segmentation and firewall rules to limit the web server's ability to make outbound requests to internal services, especially sensitive endpoints like cloud metadata services or internal APIs. 4. Employ web application firewalls (WAFs) with rules designed to detect and block SSRF attack patterns targeting the proxy_image function. 5. Monitor logs for unusual outbound HTTP requests originating from the WordPress server, particularly to internal IP ranges or unexpected external domains. 6. Conduct internal network scans to identify and secure any services that could be abused if accessed via SSRF. 7. Educate administrators and developers about SSRF risks and secure coding practices to prevent similar vulnerabilities in custom plugins or integrations. 8. Consider implementing strict input validation and allowlisting for URLs or domains that the proxy_image function can access once patched.
