  "title": "matrix-synapse: Synapse is a Matrix protocol homeserver written in Python with the Twisted framework",
  "description": "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 \u0060jwt_config.enabled\u0060 configuration setting. 2. The local password database is enabled via the \u0060password_config.enabled\u0060 and \u0060password_config.localdb_enabled\u0060 configuration settings *and* a user\u0027s 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\u0027s password after they\u0027ve 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.",
