CVE-2026-111625 · Severity: medium · CVSS 5 · Published 2026-10-16

10up Distributor is a WordPress plugin that syndicates content across a network of websites. A missing authorization check in the ajax_push() function allows users with Contributor-level permissions to publish posts on other network sites they don't have access to. An attacker with a low-privilege account could create or publish content across the entire website network, potentially spreading malicious content or defacing sites.

Technologies: 10up Distributor. Vendors: 10up.

Technical details

The ajax_push() function in push-ui.php fails to properly authorize user permissions before allowing post distribution to other network sites. A Contributor-level user can supply a chosen connection ID and post status via the dt-push nonce to create draft or published posts on sites outside their access scope. The vulnerability exists in versions before 2.3.2 and is fixed by adding proper capability checks before allowing cross-site post operations.
