Silverpeas Core 6.3.1 administrative "Bin" feature is affected by broken access control. A user with low privileges is able to navigate directly to the bin, revealing all deleted spaces. The user can then restore or permanently delete the spaces.
The "Create a Space" feature in Silverpeas Core 6.3.1 is reserved for use by administrators. This function suffers from broken access control, allowing any authenticated user to create a space by navigating to the correct URL.
