* This source only ever reads $_GET of the current request - data the |
| 44 |
* requester already controls and can see - so there is nothing to |
| 45 |
* protect and no ownership to verify. The #20359 report lists this |
| 46 |
* source as a third bypass route, but reading back the caller's own |
| 47 |
* query string discloses nothing they don't already have. |
| 48 |
* |
| 49 |
* Returned explicitly rather than deferring to Base_Source, whose |
| 50 |
* default is `! empty( $this->src() )`: that would make an empty $_GET |
| 51 |
* fail the *permission* check and throw, when the correct outcome is |
| 52 |
* simply "no such query var" - which get_result_on_prop() already |
| 53 |
* reports on its own. |
| 54 |
* |
| 55 |
* The array check is not about permission: get_result_on_prop() indexes |
| 56 |
* src() directly, so a non-array source (only reachable if a subclass |
| 57 |
* overrides query_source()) must fail here as a catchable |
| 58 |
* Preset_Exception rather than a fatal further down. |
