Authenticated SSRF via redirect-following image fetch
Published Jul 17, 2025 · Updated Oct 20, 2025
SSRF in JeeSite 5.0 through 5.12.0 allows remote authenticated users to make blind server-side requests through UEditor's image grabber. ActionEnter forwards the source[] URL list to ImageHunter.captureRemoteData(), which validates only the initial host and follows redirects with HttpURLConnection. Any authenticated account can reach the endpoint; successful requests can probe internal services or save responses only when they present an allowed image MIME type.
