Pyroscope currently allows any character to be user specified at upload. This limits that character set. It also makes sure only IDs are listed and retrieve with get, when they are fulfilling the character limit.
This validation will ensure that the generated identifiers are within the allowed set used by object stores.
Note: I don't think this is a security problem, as object store treat
..
as a "normal folder name". Also the adhoc profiles are not enabled, when there is not bucket specified.
