The vulnerability exists in the \u003ccode\u003eElementLibrary.get_resource()\u003c/code\u003e method within the \u003ccode\u003etaipy/gui/extension/library.py\u003c/code\u003e file. This vulnerability enables unauthenticated attackers to bypass intended directory restrictions, potentially leading to the exposure of sensitive files. The root cause lies in an insufficient path containment check that utilizes \u003ccode\u003estr.startswith()\u003c/code\u003e without enforcing a trailing path separator, allowing attackers to craft malicious GET requests with path traversal sequences to access files outside the intended library directory.
