xwiki contains Incorrect Authorization
Impact
It's possible to execute a script with the right of another user (provided the target user does not have programming right).
For example, the following:
{{context document="xwiki:XWiki.userwithscriptright" transformationContext="document"}}{{velocity}}Hello from Velocity!{{/velocity}}{{/context}}
written by a user not having script right (for example in the user's profile) should produce an error (the user is not allowed to write scripts). However, because of the vulnerability, if the author of the document "xwiki:XWiki.userwithscriptright" has script right (but not programming right) the script will be executed with as if it was written by the target user.
Patches
The problem has been patched in XWiki 14.8RC1, 14.4.5 and 13.10.10.
Workarounds
There's no workaround for this issue.
