Bug #103938
Updated by Daniel Siepmann about 2 months ago
Users might share URLs from the backend, e.g. <code>https://example.com/typo3/module/site/configuration/edit?site=example_site</code>
Those URLs end up in the initial start module instead of actually being opened.
This also affects custom modules by users, not only TYPO3 core modules.
The redirect only works for some routes with special hard coded handling.
The issue seems to be within <code>TYPO3\CMS\Backend\Controller\BackendController->getStartupModule()</code> where the name from redirect is used as a module instead of the actual module.
The redirect transports the route identifier, not the module identifier. Therefore the route identifier needs to be resolved to the module for proper check.
Steps to reproduce:
# Create a site
# Navigate to site module
# Edit the given site
# Copy the URL and open it within a new tab
Expected: The edit form of the site is shown
Actual: The dashboard (first module) is shown
