WordPress Elementor Plugin Server-Side Request Forgery via URL Validation Bypass

The Royal Elementor Addons plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.7.1057. This is due to insufficient validation of user-supplied URLs in the render_csv_data() function, which can be bypassed by including 'docs.google.com/spreadsheets' in a query parameter, and the subsequent use of these URLs in fopen() calls without blocking internal or private network addresses. This makes it possible for authenticated attackers, with Contributor-level access and above, to make requests to arbitrary URLs and retrieve sensitive information from internal services.

Casky was already ahead

This CVE exploits attack patterns that Casky's 312matched skills have been training on — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The Royal Elementor Addons plugin for WordPress contains a Server-Side Request Forgery (SSRF) vulnerability in its render_csv_data() function that allows authenticated attackers to make arbitrary network requests from the vulnerable server. By bypassing URL validation through the injection of 'docs.google.com/spreadsheets' in query parameters, attackers can manipulate fopen() calls to access internal network resources, private IP addresses, and sensitive services that should be restricted. This affects WordPress sites running the plugin up to version 1.7.1057 and is particularly dangerous because it requires only contributor-level privileges, a common permission level for legitimate content creators, expanding the potential attack surface significantly.

Casky's 754 security skills mapped to MITRE ATT&CK enable detection of the reconnaissance (TA0001) and credential access (TA0006) patterns inherent in SSRF exploitation. When Claude AI applies extended reasoning to this vulnerability, practitioners will observe findings aligned with techniques like T1590 (Gather Victim Network Information) as attackers probe internal services, and T1040 (Network Sniffing) patterns when internal traffic is accessed. The platform's skill-based detection identifies suspicious parameter manipulation in WordPress plugin calls, unusual fopen() invocations targeting private IP ranges or internal hostnames, and anomalous outbound connections from web server processes to restricted network segments. Security teams reviewing Casky findings for this CVE will see flagged instances of contributor accounts invoking the vulnerable render_csv_data() function with obfuscated URLs, network traffic to non-standard ports on 127.0.0.1 or private subnets, and potential exfiltration of internal service responses.
