| Package | Affected versions | Patched versions |
|---|---|---|
| moodle/moodle | ≥ 2.3, < 2.3.1 | 2.3.1 |
| moodle | = 2.3.0 |
Moodle 2.3.x before 2.3.1 uses only a client-side check for whether references are permitted in a file upload, which allows remote authenticated users to bypass intended alias (aka shortcut) restrictions via a client that omits this check.
