CVE-2026-18960Public exploitNetwork attack vector

Account block bypass via application passwords

Published Aug 10, 2026 · Updated Aug 10, 2026

Improper authentication in Dango Web Block User Account before 2.0.1 allows remote authenticated users to retain REST API access. The plugin enforces blocked status for normal password login but omits the application-password authentication path, so existing application passwords remain valid. A blocked account must already hold an application password; access remains bounded by that account's role and permits REST API reads and writes.
