  "title": "Path traversal in Wing FTP Server base-folder validation",
  "summary": "Wing FTP Server versions before 8.2.6 do not properly validate a user's configured base folder. An authenticated administrator can add script-defined directories outside that folder, allowing writes elsewhere on the host and potentially code execution as the server process owner. Exposure requires administrative access to the server's scripting-based directory configuration.",
  "mitigation": "Upgrade Wing FTP Server to version 8.2.6. Restrict administrator access and disable or tightly control scripted user-directory changes until the upgrade is complete.",
