Name of the Vulnerable Software and Affected Versions Matrix Synapse versions prior to 0.34.0.1

Description The issue allows remote attackers to impersonate users due to the use of a predictable value to derive a secret key and other secrets when the macaroon secret key authentication parameter is not set.

Recommendations For versions prior to 0.34.0.1, update to version 0.34.0.1 or later to resolve the issue. As a temporary workaround, consider setting the macaroon secret key authentication parameter to a unique and unpredictable value to minimize the risk of exploitation.
