  "details": "ideon is a self-hosted visual workspace. Prior to version 0.9.5, ideon's link-preview endpoint requires no authentication at all and forwards any URL a caller supplies straight into a server-side fetch. The app does have a general-purpose SSRF guard (safeFetch/validateSafeUrl in src/app/lib/ssrf.ts), but this route sits behind no login check whatsoever, making it a fully open, anonymous URL-fetch relay - and the guard's IP blocklist itself has a gap that lets it reach the server's own loopback interface via the 0.0.0.0 \"any address\" bypass, a well-documented SSRF-filter evasion technique on Linux. This issue has been patched in version 0.9.5.",
