Path traversal vulnerability. If a user generated a client using a maliciously crafted OpenAPI document, it is possible for generated files to be placed in arbitrary locations on disk.
Giving this a CVSS score of 3.0 (Low) with CVSS:3.0/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N/E:P/RL:U/RC:C
A fix is being worked on for version 0.5.3
Inspect OpenAPI documents before generating clients for them.
