CVE-2021-24927

The My Calendar plugin versions prior to 3.2.18 contains a reflected cross-site scripting vulnerability in the mc_post_lookup AJAX action. Any logged-in user can exploit this flaw by injecting malicious scripts through the callback parameter, which the plugin fails to properly sanitize and escape before returning in the response. This allows attackers to execute arbitrary JavaScript in the browsers of other users who interact with the crafted payload.
