      "value": "nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.3, every /ui/* POST / PUT / PATCH / DELETE route processes the request as soon as the session cookie validates. SameSite=Lax on the session cookie prevents most cross-site form submits but does not protect: top-level form-submit navigations from third-party pages (some browsers still send Lax cookies on top-level POSTs); same-registrable-domain attackers (sibling-subdomain XSS, subdomain takeover); the GET /ui/logout route, which a third-party <img src=\".../ui/logout\"> can force-trigger. This issue has been patched in version 0.3.3."

Antes de la versión 0.3.3, cada ruta /ui/* POST / PUT / PATCH / DELETE procesa la solicitud tan pronto como la cookie de sesión valida. SameSite=Lax en la cookie de sesión previene la mayoría de los envíos de formularios entre sitios, pero no protege: las navegaciones de envío de formularios de nivel superior desde páginas de terceros (algunos navegadores aún envían cookies Lax en POSTs de nivel superior); atacantes del mismo dominio registrable (XSS de subdominio hermano, toma de control de subdominio); la ruta GET /ui/logout, que un tercero <img src=’... / ui/logout’> puede forzar a activar. Este problema ha sido parcheado en la versión 0.3.3."
