What is CVE-2026-103980?

The ideon visual workspace exhibits a server-side request forgery (SSRF) vulnerability due to insufficient IPv6 address handling in its safeFetch mechanism. This vulnerability allows authenticated users to exploit the isPrivateIP function, which fails to recognize a range of IPv6 encodings that map to private IPv4 addresses. Consequently, an attacker could use these addresses in URLs to access cloud metadata endpoints, local server services, and internal RFC 1918 networks. This issue has been addressed in version 0.9.6, so users are strongly advised to upgrade to the latest version to safeguard their applications.

Affected Version(s)
