pyLoad: User Can Access Data After Permission Changes
GHSA-fj52-5g4h-gmq8
Summary
If an administrator changes a user's permissions, the user's session may still allow them to access data they shouldn't. This means a user who loses access to certain features can still use a valid session to access them. To fix this, administrators should manually log out users when changing their permissions.
What to do
No fix is available yet. Check with your software vendor for updates.

Original title
pyLoad's Session Not Invalidated After Permission Changes
Original description
### Summary
The `pyload` application does not properly invalidate or modify sessions upon changes made to a user's permissions.
### Details
Whenever an administrator changes the permissions a specific account has, they do not expect that account still being able to access data that their new permissions do not allow. This is not the case for the `pyload` application, as a user with a valid session can still perform the actions.
### PoC
Take a user with all the permissions, as shown below.
We now log in as this user.
Let us now take away all the permissions.
The logged in session can still be used to access everything in the application.
### Impact
Should permissions be taken away, then the user is expected not to be able to execute the actions belonging to those actions anymore.
