CVE-2026-25495: Craft CMS Vulnerable to SQL Injection in Element Indexes via `criteria[orderBy]`

The element-indexes/get-elements endpoint is vulnerable to SQL Injection via the criteria[orderBy] parameter (JSON body). The application fails to sanitize this input before using it in the database query. An attacker with Control Panel access can inject arbitrary SQL into the ORDER BY clause by omitting viewState[order] (or setting both to the same payload).

[!NOTE] The ORDER BY clause executes per row. SLEEP(1) on 10 rows = 10s delay.
