Advanced Views REST routes expose administrator-authored templates to Subscribers

Advanced Views through 3.9.1 registers REST routes that let a Subscriber-or-higher user retrieve editor content for any Layout or Post Selection record. Responses can expose administrator-authored template markup, CSS, JavaScript and PHP controller variables; the record identifies register_rest_routes but not the exact routes or identifiers.

Weakness
CWE-862 — Missing Authorization

This CVE was published Aug 01, 2026 and is one of 3 known issues for this plugin.

What to do

Update, patch or deactivate.

Update to a corrected release after 3.9.1. Review Subscriber REST activity, determine which templates were exposed, and rotate secrets embedded in controller variables or templates.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
