Many Notes: Path Traversal via ZIP import allows arbitrary file write and stored XSS in other users' vaults
CVSS 3.1
9.6Critical
Official description
Many Notes is a Markdown note-taking web application designed for simplicity. Prior to 0.16.0, the ZIP vault import implemented in app/Actions/ProcessImportedVault.php accepts archive filenames containing parent-directory traversal segments. An authenticated user can write arbitrary files outside the importing user's vault and into other users' vaults, including overwriting existing files. Disguised SVG content can be placed in another user's vault and execute stored cross-site scripting when the victim opens that vault. This issue is fixed in version 0.16.0.
