CVE-2025-62254

⚠️ An attacker can exploit the ComboServlet in Liferay Portal to launch a denial of service attack by simply crafting a long query string — no authentication needed! 💥 Think of it like an email inbox that lets anyone send you massive files without any limits. Over time, these giant attachments can clog up your inbox and make it impossible to receive new messages — that’s exactly what can happen with this vulnerability. If an attacker successfully sends large responses, they could overwhelm the server, leading to sluggish performance or even a complete crash. This could disrupt your services and leave your users frustrated until the issue is resolved!

If an attacker successfully sends large responses, they could overwhelm the server, leading to sluggish performance or even a complete crash.
