Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Any user can edit his own profile and inject code which is going to be executed with programming right.
Steps to reproduce:
* Set your first name to
```
{{cache id="userProfile"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/cache}}
```
The first name appears as interpreted "`Hello from groovy`" instead of the expected fully escaped "`{{cache id="userProfile"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/cache}}`".
The same vulnerability can also be exploited in all other places where short text properties are displayed, e.g., in apps created using [Apps Within Minutes](https://extensions.xwiki.org/xwiki/bin/view/Extension/App%20Within%20Minutes%20Application) that use a short text field.
### Patches
The problem has been patched on versions 13.10.9, 14.4.4, 14.7RC1.
### Workarounds
There are no other workarounds than upgrading XWiki or patching the xwiki-commons-xml JAR file.
