CVE-2026-44680: MikroORM has SQL injection via runtime-controlled identifiers and JSON-path keys

MikroORM’s identifier-quoting helper (Platform.quoteIdentifier and the postgres/mssql overrides) and its JSON-path emitters (Platform.getSearchJsonPropertyKey, quoteJsonKey) did not properly escape characters that delimit the SQL identifier or string-literal context they emit into. When application code passes attacker-influenced strings to public ORM APIs that expect an identifier or a JSON-property filter, an attacker can break out of the quoted context and inject arbitrary SQL.
