This CVE was published Aug 10, 2026 and is one of 36 known issues for this plugin.
Update, patch or deactivate.
No fixed release is identified by the authoritative advisory. Update when the vendor publishes a confirmed fixed version. Until then, disable affected public booking modifications or deactivate the plugin when warranted, and reconcile stored booking totals against payment and order records.
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
