GitHub AdvisoriesGHSA-cx45-565q-6qx8
SilverStripe Subsite weakens file permissions
The subsites module can weaken edit restrictions on some files and allow a malicious user to edit files they do not have edit rights to.
This only affects projects with the subsites module installed. Regression testing should focus on custom file logic.
Be advised that this is not a case of a user being able to edit a file in subsites they do not have access to. As a reminder, all separation of content achieved with the subsites module should be viewed as cosmetic and not appropriate for security-critical applications.
