CVE-2026-4361Network attack vector

Internal-service probing via unrestricted remote image fetch

Published Sep 5, 2026 · Updated Sep 7, 2026

Server-side request forgery in Elegant Themes Divi 4.27.6 and earlier allows remote authenticated users to probe internal services. The et_pb_set_video_oembed_thumbnail_resolution() function passes a Contributor-controlled image_src URL to wp_remote_get(), which accepts private and reserved destinations. Contributor-level access exposes blind HTTP-status and timing oracles for determining whether internal targets respond; response bodies are not disclosed.
