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.

 https://cve.radiocsirt.org/vuln/ghsa-26c5-ppr8-f33p GHSA-26c5-ppr8-f33p — Synapse has improper checks for deactivated users during login 2026-10-08T16:39:12.226657+00:00

Affected: PyPI: matrix-synapse

### Impact It may be possible for a deactivated user to login when using uncommon configurations.

This only applies if any of the following are true:

* [JSON Web Tokens are enabled for login](https://matrix-org.github.io/synapse/latest/jwt.html) via the `jwt_config.enabled` configuration setting * The [local password database is enabled](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#password_config) via the `password_config.enabled` and `password_config.localdb_enabled` configuration settings *and* a user's password is [updated via an admin API](https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#create-or-modify-account) 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.

### Patches

* If using JSON Web Token logins: #15624 * For other users: #15634

### Workarounds

If not using JSON Web Tokens, ensure that deactivated users do not have a password set. This list of users can be queried from PostgreSQL:

```sql SELECT name FROM users WHERE password_hash IS NOT NULL AND deactivated = 1; ```
