Technical details

This is an improper authorization (CWE-285) vulnerability in the Platform API's DELETE handlers for six content resources. The endpoints verify workspace membership but fail to check resource ownership or user role, allowing members to bypass documented restrictions. An authenticated workspace member with low privileges can perform DELETE operations on any workspace resource via network requests without additional user interaction.
