Copyparty: file/dirkey confusion

AI Analysis

No AI analysis yet.

Description

Copyparty is a portable file server. Prior to 1.20.17, copyparty volumes with the dk or dks directory-key flag combined with the fk or fka file-key flag can convert a valid file key into a directory key, granting read access to the containing folder even though both features are disabled by default and must be explicitly enabled in the volume flags. This issue is fixed in version 1.20.17.
