CVE-2025-5818Network attack vector

Internal service access via unrestricted image URLs

Published Jul 23, 2025 · Updated Apr 8, 2026

SSRF in Featured Image Plus 1.6.6 and earlier allows remote authenticated users to access internal services through crafted image URLs. The fip_get_image_options function accepts an administrator-controlled image URL and issues a server-side request without restricting its destination. Administrator access is required, and successful exploitation permits requests that query or modify information exposed by internal services.
