AI Analysis
Technical Summary
CVE-2026-16546 is a missing authorization vulnerability (CWE-862) in the Wired Impact Volunteer Management WordPress plugin prior to version 2.8.2. The plugin fails to perform authorization checks in an AJAX action responsible for removing RSVPs. Consequently, any user with a Subscriber role can remove arbitrary RSVPs from any volunteer opportunity, potentially disrupting volunteer management processes.
Potential Impact
