Vulnerability Title
Denial of Service in fzf
Vulnerability Description
fzf is vulnerable to a Denial of Service (DoS) due to inefficient HTTP body processing in the --listen mode due to inefficient HTTP body processing using repeated string concatenation, resulting in quadratic time complexity (O(n²)). A crafted POST request with many small segments can trigger excessive CPU usage during request handling.This allows a single malicious request to monopolize the single‑threaded HTTP server, blocking all other clients and resulting in denial of service. This issue was fixed in version 0.73.1.

Vulnerability Title
fzf 资源管理错误漏洞
Vulnerability Description
fzf fzf是fzf个人开发者的一款通用命令行模糊搜索工具。 fzf 0.73.1之前版本存在资源管理错误漏洞,该漏洞源于--listen模式下HTTP body处理效率低下,使用重复字符串拼接导致二次时间复杂度(O(n²)),可能导致精心构造的POST请求触发处理期间CPU过度使用,使单一恶意请求独占单线程HTTP服务器,阻止其他所有客户端,从而造成拒绝服务。
