The primary mitigation for CVE-2025-2803 is to upgrade to a patched version of the So-Called Air Quotes plugin as soon as it becomes available. Until then, consider implementing temporary workarounds. A Web Application Firewall (WAF) can be configured to block requests containing suspicious shortcodes or patterns. Additionally, restrict access to the plugin's administrative interface to authorized users only. Monitor WordPress plugin activity logs for any unusual shortcode executions. After upgrading, verify the fix by attempting to execute a known malicious shortcode and confirming that it is blocked.
