Path Traversal in CISA Thorium download_ephemeral and download_children
CVE-2025-35430 is a path traversal vulnerability in CISA Thorium. According to the provided content, Thorium does not adequately validate the paths of downloaded files in the 'download_ephemeral' and 'download_children' functionality. As a result, a remote authenticated attacker can manipulate file paths and access arbitrary files, subject to the permissions of the Thorium process and underlying file system. The issue stems from insufficient path validation on downloaded file handling, allowing traversal outside the intended directory scope.
