JSON

Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. In affected versions it may be possible for a deactivated user to login when using uncommon configurations. This only applies if any of the following are true: 1. JSON Web Tokens are enabled for login via the jwt_config.enabled configuration setting. 2. The local password database is enabled via the password_config.enabled and password_config.localdb_enabled configuration settings and a user’s password is updated via an admin API after a user is deactivated. Note that the local password database is enabled by default, but it is uncommon to set a user’s password after they’ve been deactivated. Installations that are configured to only allow login via Single Sign-On (SSO) via CAS, SAML or OpenID Connect (OIDC); or via an external password provider (e.g. LDAP) are not affected. If not using JSON Web Tokens, ensure that deactivated users do not have a password set. This issue has been addressed in version 1.85.0. Users are advised to upgrade.
