| 설명 | Severity: High · CWE: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
Affected versions:v1.4.0
Summary
The chunk-check endpoint joins the request body's name field directly into a file path and returns whether that file exists and whether its size matches a caller-supplied value. Because name is not filtered, a caller can supply ../ sequences or an absolute path to probe for the existence of arbitrary files anywhere on the host and learn their exact size. The controller is marked @Deprecated and @Hidden (excluded from the Swagger UI) but is still mapped and reachable; no URI-level authorization is enforced for it. |
