CVE-2026-54598Public exploitNetwork attack vector

Unauthenticated schema mutation via unguarded migration endpoint

Published Aug 31, 2026 · Updated Sep 2, 2026

Missing authentication in ellite Wallos before 4.9.4 allows remote attackers to run pending schema migrations through an HTTP endpoint. The endpoints/db/migrate.php handler opens the live SQLite database and loads each pending migration without checking session state, user identity, or an authorization guard. Network reachability to the endpoint is sufficient; exploitation mutates the live schema through pending DDL operations, while code execution additionally requires a separate file-write primitive.
