Weakness
CWE-799 — Improper Control of Interaction Frequency

This CVE was published Oct 06, 2026 and is one of 45 known issues for this plugin.

Update, patch or deactivate.

Update WP Event Solution to 4.1.26 or a later supported release. Application-level remediation: Enforce the appropriate capability and object-level permission before reading or changing protected state; a nonce alone is not authorization.

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.
