Visualizer lets contributors delete any chart
Visualizer before 4.0.6 authorizes chart deletion with only a site-wide capability check and does not verify ownership of the requested chart. A Contributor or higher role can therefore permanently delete charts belonging to any user, including administrators. The authoritative export does not identify the deletion action, endpoint, or chart identifier parameter.

- CWE-862 — Missing Authorization
This CVE was published Sep 11, 2026 and is one of 18 known issues for this plugin.
Update, patch or deactivate.
Update Visualizer to 4.0.6 or later. The authoritative export marks versions below 4.0.6 affected. The application-level fix must verify both the required capability and object-level ownership or an explicit permission to delete the selected chart.
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.
Technical description
The Visualizer WordPress plugin before 4.0.6 does not properly authorise chart-deletion requests, performing only a site-wide capability check with no per-object ownership verification, allowing users with the Contributor role and above to permanently delete any chart on the site, including charts created by other users such as administrators.
