### Impact

One can ask for any file located in the classloader using the template API and a path with “..” in it. For example

“`
{{template name=”../xwiki.hbm.xml”/}}
“`

To our knownledge none of the available files of the classloader in XWiki Standard contain any strong confidential data, hence the low confidentiality value of this advisory.

### Patches

The issue is patched in versions 14.0 and 13.10.3.

### Workarounds

There’s no easy workaround for this issue, administrators should upgrade their wiki.
