Configure the com.glide.attachment.max_size property to control the maximum size (in megabytes) permitted for an
uploaded attachment.
This property controls the maximum size (in megabytes) of an uploaded attachment. If this property is not set to the recommended value of 1024 (1 gigabyte) or less, the platform can accept large files that
could fill up storage and lead to a Denial of Service (DoS) attack.
