Details

AuthRestServlet in Matrix Synapse before 1.21.0 is vulnerable to XSS due to unsafe interpolation of the session GET parameter. This allows a remote attacker to execute an XSS attack on the domain Synapse is hosted on, by supplying the victim user with a malicious URL to the /matrix/client/r0/auth/*/fallback/web or /matrix/client/unstable/auth/*/fallback/web Synapse endpoints.
