CVE-2026-19050Network attack vector

Subscriber-level SSRF via unchecked URL validation

Published Aug 12, 2026 · Updated Aug 12, 2026

Server-side request forgery in ProSolution WP Client before 2.0.9 allows remote authenticated users to access internal services. The proSol_url_validate AJAX handler accepts an unvalidated URL and invokes the WordPress HTTP client without a capability or nonce check. Subscriber-level access is sufficient to make the WordPress host contact internal or metadata endpoints with attacker-controlled request details.
