XWiki Platform is a generic wiki platform. Starting in version 3.0-milestone-1, it's possible to execute a script with the right of another user, provided the target user does not have programming right. The problem has been patched in XWiki 14.8-rc-1, 14.4.5, and 13.10.10. There are no known workarounds for this issue.

GHSA-859x-p6jp-rc2w — xwiki contains Incorrect Authorization

Affected: Maven: org.xwiki.platform:xwiki-platform-rendering-macro-context

### 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.
