XWiki Commons are technical libraries common to several other top level XWiki projects. The Document script API returns directly a DocumentAuthors allowing to set any authors to the document, which in consequence can allow subsequent executions of scripts since this author is used for checking rights. The problem has been patched in XWiki 14.10 and 14.4.7 by returning a safe script API.
The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.

When a product contains certain functions that perform operations requiring an elevated level of privilege, the caller of a privileged API must be careful to:
If the caller of the API does not follow these requirements, then it may allow a malicious user or process to elevate their privilege, hijack the process, or steal sensitive data. For instance, it is important to know if privileged APIs do not shed their privileges before returning to the caller or if the privileged function might make certain assumptions about the data, context or state information passed to it by the caller. It is important to always know when and how privileged APIs can be called in order to ensure that their elevated level of privilege cannot be exploited.
