CVE-2026-64826
rConfig < 8.2.13 Path Traversal File Read via FileDownloadController
rConfig before 8.2.13 contains a path traversal vulnerability that allows authenticated attackers to read arbitrary files by supplying unsanitized directory traversal sequences in the filename GET parameter of the download_export() method.
