wire-server is an open-source back end for Wire, a secure collaboration platform. Before version 2.106.0, the CORS Access-Control-Allow-Origin
header set by nginz
is set for all subdomains of .wire.com
(including wire.com
). This means that if somebody were to find an XSS vector in any of the subdomains, they could use it to talk to the Wire API using the user’s Cookie. A patch does not exist, but a workaround does. To make sure that a compromise of one subdomain does not yield access to the cookie of another, one may limit the Access-Control-Allow-Origin
header to apps that actually require the cookie (account-pages, team-settings and the webapp).
