## Overview

Plane is an open-source project management tool. Prior to 1.4.0, the fix for CVE-2026-27706 and GHSA-jcc6-f9v6-f7jw, an SSRF in work-item link unfurling shipped in v1.2.2, remains incomplete in the v1.3.1 GA release. Any authenticated project member can make the server fetch attacker-selected internal targets, including cloud metadata at 169.254.169.254, and read the response body returned as the link title or favicon. Complete hardening exists on main in PR 9163 but was not included in an earlier released tag. This issue is fixed in 1.4.0.
