Unauthenticated SSRF via unrestricted font URL fetch
Published Apr 9, 2024 · Updated Apr 8, 2026
SSRF in Everest Forms 2.0.7 and earlier allows remote attackers to issue server-side requests through the font_url parameter. The unauthenticated everest_forms_get_local_font_url AJAX action accepts a crafted font_url and passes it to the local-font downloader without restricting the destination. The Load Fonts Locally option must be enabled; successful requests can reach internal services and read or modify their data.
