Fiderを複数組織向けのマルチテナント構成で運用していると、別の組織のボードに不正にログインされるおそれがあります。0.36.0で修正済みのため、HOST_MODEの設定を確認し、該当すれば更新してください。

Original description The description as published by the source.

Fider is a feedback portal for feature requests and suggestions. Prior to version 0.36.0, in multi-tenant mode (HOST_MODE=multi), an attacker can use an email verification key issued by Tenant A to authenticate as the same email address on Tenant B. This completely bypasses tenant isolation and allows unauthorized account takeover across tenants. Single-host deployments (HOST_MODE=single, the default) are NOT affected. This issue has been patched in version 0.36.0.
