CVE-2026-14923: CWE-863 Incorrect Authorization in Sync Post With Other Site
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.
AI Analysis
Technical Summary
CVE-2026-14923 describes an incorrect authorization vulnerability (CWE-863) in the Sync Post With Other Site WordPress plugin prior to version 1.9.3. The flaw arises from an operator-precedence mistake in the authorization logic of a REST API endpoint responsible for creating and updating posts. As a result, authenticated users with only the post-editing capability—typically Contributors—can bypass intended restrictions and create, publish, or overwrite Pages, including those authored by users with higher privileges. This elevates the ability of lower-privileged users to modify content beyond their intended scope.
Potential Impact
An authenticated user with limited post-editing rights can create, publish, and overwrite arbitrary Pages, including those created by higher-privileged users. This could lead to unauthorized content modification and potential content integrity issues within the affected WordPress sites.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict the assignment of post-editing capabilities to trusted users only. Monitor for updates from the plugin vendor regarding a security patch addressing this authorization flaw.
