CWE-862 — Missing Authorization

This CVE was published Aug 06, 2026 and is one of 4 known issues for this plugin.

Update, patch or deactivate.

No fixed release is identified. Deactivate the plugin until a verified release newer than 6.1.1 is available or remove Contributor access from untrusted accounts.

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.
