Summary

CVE-2024-13924 is a medium-severity SSRF (CWE-918) vulnerability in Fancywp Starter Templates. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 34th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2024-13924 is a Blind Server-Side Request Forgery (SSRF) vulnerability, classified under CWE-918, in the Starter Templates by FancyWP plugin for WordPress. It affects all versions up to and including 2.0.0 and stems from inadequate validation via the 'http_request_host_is_external' filter. Published on March 8, 2025, the issue has a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), reflecting medium severity with low confidentiality impact.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction required. By triggering the flawed filter, they can force the web server to originate requests to arbitrary external locations, enabling blind SSRF attacks. This could allow querying or modifying data from internal services that are not directly accessible from the internet.

Advisories from Wordfence provide detailed threat intelligence on the vulnerability, while the WordPress plugin trac repository shows the relevant code in class-export.php. Mitigation likely involves updating the plugin beyond version 2.0.0, as earlier versions remain vulnerable.

Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
