An issue in the relPath parameter of WebFileSys version 2.31.0 allows attackers to perform directory traversal via a crafted HTTP request. By injecting traversal payloads into the parameter, attackers can manipulate file paths and gain unauthorized access to sensitive files, potentially exposing data outside the intended directory.
