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."}],"source":{"advisory":"GHSA-26c5-ppr8-f33p","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T15:25:36.434Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/matrix-org/synapse/security/advisories/GHSA-26c5-ppr8-f33p","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/matrix-org/synapse/security/advisories/GHSA-26c5-ppr8-f33p"},{"name":"https://github.com/matrix-org/synapse/pull/15624","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/matrix-org/synapse/pull/15624"},{"name":"https://github.com/matrix-org/synapse/pull/15634","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/matrix-org/synapse/pull/15634"},{"name":"https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#create-or-modify-account","tags":["x_refsource_MISC","x_transferred"],"url":"https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#create-or-modify-account"},{"name":"https://matrix-org.github.io/synapse/latest/jwt.html","tags":["x_refsource_MISC","x_transferred"],"url":"https://matrix-org.github.io/synapse/latest/jwt.html"},{"name":"https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#password_config","tags":["x_refsource_MISC","x_transferred"],"url":"https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#password_config"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/X6DH5A5YEB5LRIPP32OUW25FCGZFCZU2/","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-01-07T16:28:39.349896Z","id":"CVE-2023-32682","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-01-07T16:28:59.980Z"}}]}}
