Published Nov 13, 2023 · Updated Apr 28, 2026

SSRF in Blubrry PowerPress 11.0.6 and earlier allows remote authenticated users to access internal services via a media URL. The wp_ajax_powerpress_media_info action makes server-side requests to attacker-supplied media URLs without adequate destination checks. Contributor-level access is required; requests originate from WordPress and can query or modify information exposed by reachable internal services.
