Unauthenticated Local File Inclusion in WP Cafe Pro

CVE-2026-66587 is a critical unauthenticated Local File Inclusion (LFI) vulnerability affecting WP Cafe Pro versions below 3.0.15. This vulnerability allows attackers to read arbitrary files from the affected server without authentication, potentially exposing sensitive configuration files, database credentials, and other confidential data. WordPress plugin vulnerabilities are particularly concerning because they affect thousands of websites simultaneously, and the unauthenticated nature of this flaw means any attacker on the internet can exploit it without prior access or credentials. Organizations running vulnerable versions of WP Cafe Pro face immediate risk of information disclosure that could lead to further compromise.

While this CVE currently maps to zero Casky skills due to its novelty, Claude AI's extended reasoning capabilities within the Casky platform excel at identifying the attack patterns and exploitation chains associated with LFI vulnerabilities. Practitioners using Casky would leverage skills mapped to techniques like T1083 (File and Directory Discovery), T1005 (Data from Local System), and T1012 (Query Registry) to detect reconnaissance and data exfiltration attempts targeting the vulnerable endpoint. Through behavioral analysis, the platform would flag suspicious file traversal patterns in web server logs—such as repeated requests containing path traversal sequences (../, ..\, or encoded variants)—combined with access attempts to sensitive files like wp-config.php, .env, or /etc/passwd. As this vulnerability gains traction and threat intelligence matures, Casky will integrate new skills to provide real-time detection of exploitation attempts and help practitioners rapidly patch and monitor their WordPress installations.
