Vulnerability Title
Phalcon: Catastrophic backtracking (ReDoS) in the default Phalcon Router route lead to remote unauthenticated DoS
Vulnerability Description
Phalcon is a high-performance, full-stack PHP framework. Prior to 5.15.0, every Phalcon MVC application built with a default router registers a built-in route whose compiled PCRE pattern contains the nested quantifier (/.), and the same construct is produced by the /:params placeholder and the CLI router. Phalcon\Mvc\Router::handle() matches this pattern against the attacker-controlled request URI on every request, so a crafted path such as one containing repeated slashes followed by decoded newlines can trigger catastrophic backtracking and cause CPU exhaustion or route-matching failure. This issue is fixed in version 5.15.0.

Vulnerability Title
Phalcon 资源管理错误漏洞
Vulnerability Description
Phalcon Phalcon是Phalcon公司开源的一个以 C 扩展形式交付的高性能、全栈 PHP 框架,能显著降低资源消耗。 Phalcon 5.15.0之前版本存在资源管理错误漏洞,该漏洞源于默认路由器注册的内置路由中嵌套量词导致PCRE编译的正则表达式模式,使得攻击者可通过包含重复斜杠和解码换行符的特制路径触发灾难性回溯,从而造成CPU耗尽或路由匹配失败。
