Versions 0.3.0 through 0.10.0 have a path traversal vulnerability in LeafWiki\u2019s asset rename functionality.

This could allow sensitive local files, such as the application database, to become downloadable as page assets. Users should update to version 0.10.1 or greater. As an additional mitigation, operators should ensure that the LeafWiki process runs with the least privileges necessary and does not have filesystem access to sensitive files outside the application\u2019s required directories. Until a patch is applied, operators may reduce risk by restricting editor access to trusted users only and by limiting the filesystem permissions of the LeafWiki process."}, {"lang": "es", "value": "LeafWiki es una wiki autoalojada.
