This CVE was published Oct 05, 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. An application-level fix should address the following: Enforce the intended capability and object-level permission server-side before accessing or changing a protected resource. A nonce alone is not an authorization check.
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.
