CVE-2026-14923 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
