Short explanation
CVE-2026-104108 affects the FileRise OIDC login mechanism. FileRise versions prior to 3.23.0 map authenticated OIDC identities to local accounts using mutable claims without requiring email_verified, allowing potential compromise of existing local accounts.
Attackers can obtain provider-issued claims that collide with existing local usernames or built-in administrator accounts, leading to unauthorized access.
What should be done?
- Review the vendor advisory for further instructions
- Apply available updates when possible
- Audit identity provider configurations
Chain of evidence and sources
FileRise 3.23.0 öncesi sürümler, OIDC kimliğini yerel bir hesaba bağlarken mutable preferred_username veya email taleplerini kullanır.
Sistem, e-posta tabanlı adlandırma için email_verified doğrulamasını zorunlu kılmamaktadır.
Saldırgan, yerleşik yönetici dahil olmak üzere mevcut bir yerel hesap olarak oturum açabilir.
Show the technical text from the sources
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise maps an authenticated OIDC identity to a local account using mutable preferred_username or email claims and does not require email_verified for email-based naming. An attacker who can obtain provider-issued claims colliding with an existing local username can be logged in as that account, including the built-in administrator, even when automatic provisioning is disabled. Exploitability depends on the configured identity provider allowing the colliding claim. This issue is fixed in version 3.23.0.
