Detailsinfo

A vulnerability was found in 3xpyth0n ideon up to 0.9.4. It has been classified as critical. This affects the function validateSafeUrl of the file src/app/lib/ssrf.ts of the component Link-Preview Endpoint. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-68507 since 07/30/2026. The exploitability is told to be easy.
