Recommendation: Plan a near-term fix — a public PoC already exists.

OpenKM 6.3.12 contains an unrestricted SQL execution vulnerability that allows authenticated administrative users to execute arbitrary SQL statements against the application database via the DatabaseQuery interface. Attackers can submit malicious SQL queries through the qs parameter to the /admin/DatabaseQuery endpoint to extract sensitive data including usernames and password hashes from the OKM_USER table, modify permissions, or delete database records.
