Silverstripe Admin provides a basic management interface for the Silverstripe Framework. In versions on the 1.x branch prior to 1.13.19 and on the 2.x branch prior to 2.1.8, users who don't have edit or delete permissions for records exposed in a `ModelAdmin` can still edit or delete records using the CSV import form, provided they have create permissions. The likelihood of a user having create permissions but not having edit or delete permissions is low, but it is possible.

TinyMCE 4.x is vulnerable to several XSS vectors, which had been patched in later versions. Two of these have been identified as affecting silverstripe/admin.
