CVE-2026-27706
Plane is an an open-source project management tool. Prior to version 1.2.2, a Full Read Server-Side Request Forgery (SSRF) vulnerability has been identified in the "Add Link" feature. This flaw allows an authenticated attacker with general user privileges to send arbitrary GET requests to the internal network and exfiltrate the full response body. By exploiting this vulnerability, an attacker can steal sensitive data from internal services and cloud metadata endpoints. Version 1.2.2 fixes the issue.

Antes de la versión 1.2.2, se ha identificado una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) de lectura completa en la característica 'Add Link'. Esta falla permite a un atacante autenticado con privilegios de usuario generales enviar peticiones GET arbitrarias a la red interna y exfiltrar el cuerpo completo de la respuesta. Al explotar esta vulnerabilidad, un atacante puede robar datos sensibles de servicios internos y puntos finales de metadatos en la nube. La versión 1.2.2 corrige el problema."
