Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
The table access voter in the back end doesn't check if a user is allowed to access the corresponding module.
### Patches
Update to Contao 5.3.38 or 5.6.1.
### Workarounds
Do not rely solely on the voter and additionally check `USER_CAN_ACCESS_MODULE`.
