WordPress Plugin SSRF via Unvalidated AJAX URL Fetching

The SmartAIPress WordPress plugin through 1.2.0 does not perform a capability check on one of its AJAX actions and does not validate a user-supplied URL before fetching it server-side, allowing users with subscriber-level access and above to make the site retrieve arbitrary internal or external URLs and read the response, resulting in a full-read Server-Side Request Forgery.

Casky was already ahead

This CVE exploits attack patterns that Casky's 331matched skills already investigate — 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

SmartAIPress WordPress plugin versions through 1.2.0 contain a critical Server-Side Request Forgery (SSRF) vulnerability in its AJAX handlers. The plugin fails to implement capability checks on sensitive actions and does not validate URLs before performing server-side retrieval, allowing attackers with subscriber-level privileges to force the site to fetch arbitrary URLs and read responses. This vulnerability affects any WordPress installation running the vulnerable plugin, exposing internal services, metadata endpoints, cloud credentials, and sensitive network resources that should never be directly accessible from the internet.

Casky's 331 matching security skills leverage Claude AI's extended reasoning to identify attack patterns associated with MITRE ATT&CK techniques TA0001 (Initial Access) and TA0006 (Execution). Practitioners using Casky will detect suspicious patterns including: unauthenticated or low-privilege AJAX requests with embedded URL parameters, server-initiated outbound connections to internal IP ranges (169.254.169.254, 127.0.0.1) or administrative interfaces, unusual response times indicating remote fetching, and data exfiltration through plugin response handlers. The platform's skill mapping surfaces indicators of exploitation attempts targeting credential endpoints, internal service enumeration, and reconnaissance activities that precede lateral movement, enabling security teams to identify and block SSRF attacks before sensitive internal resources are compromised.
