CVE-2026-10526Public exploitNetwork attack vector

Unauthenticated blind SSRF via unchecked oEmbed URLs

Published Aug 4, 2026 · Updated Aug 4, 2026

Server-side request forgery in WPDeveloper EmbedPress before 4.6.1 allows remote attackers to make the WordPress server request internal services. The unauthenticated oEmbed REST and admin-ajax endpoints pass attacker-supplied URLs to WordPress oEmbed discovery without excluding uncovered internal ranges. No account or interaction is required; responses stay hidden, but timing reveals whether the server reached internal targets.
