## Affected

- Unknown Sync Post With Other Site: fixed in 1.9.3

## Description

The Sync Post With Other Site WordPress plugin before 1.9.3 does not correctly enforce the page-editing capability on a REST route that creates and updates posts, because of an operator-precedence flaw in its authorization check. An authenticated user holding only the post-editing capability (such as a Contributor) can create, publish, and overwrite arbitrary Pages, including modifying content authored by higher-privileged users.
