CVE-2026-55500 is a vulnerability in decolua 9Router affecting versions prior to 0.4.80. The flaw resides in the /api/settings/database functionality, which permits full database export and full database import with insufficient access control. In affected versions, the protection applied to this endpoint relies only on the ALWAYS_PROTECTED middleware check, which validates a JWT or CLI token but does not enforce adequate authentication or authorization for such highly sensitive administrative operations. As a result, an attacker can export the entire database, including stored credentials, API keys, OAuth tokens, and application settings, or import a replacement database that completely overwrites existing data. The issue was fixed in version 0.4.80.
