Name of the Vulnerable Software and Affected Versions Budibase versions prior to 3.40.0
Description Authenticated builders can upload files containing traversal sequences in S3 object keys because the software fails to properly sanitize them. These sequences are preserved during workspace export, allowing attackers to use filenames with .. segments to escape the temporary directory and write arbitrary content to any path accessible by the Budibase process.
Recommendations Update to version 3.40.0 or later.
