What is CVE-2026-27706?

The Plane project management tool has a critical vulnerability in its 'Add Link' feature, which allows an authenticated user to exploit Server-Side Request Forgery (SSRF). This flaw enables attackers with general user privileges to send arbitrary GET requests, potentially targeting the internal network. By exploiting this vulnerability, sensitive data from internal services and cloud metadata endpoints can be accessed and exfiltrated. An updated version, 1.2.2, addresses this security issue.
