CVE-2026-28423Network attack vector

Unauthenticated internal resource access via Glide URLs

Published Feb 27, 2026 · Updated Feb 27, 2026

Server-side request forgery in Statamic CMS before 5.73.11 and 6.0.0 through 6.3.x allows remote attackers to request arbitrary URLs. In insecure Glide mode, the image proxy accepts untrusted source or watermark URLs and fetches them without restricting destinations to publicly routable hosts. The non-default mode is required; successful requests can expose data from internal services, cloud metadata endpoints, and other resources reachable from the CMS host.
