建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在 PeaZip 10.5.0 至 11.2.0（Windows 版本）中，归档对象查看器（peach.pas、grid_obj_open）的“危险扩展确认”机制存在禁用输入列表不完整的问题（CWE-184）。攻击者可通过诱使受害者打开一个精心构造的归档文件中的某个条目，在无确认对话框的情况下执行任意程序或任意命令。 该确认提示（“您是否要运行此文件？”）依赖于 SECEXTCONST，这是一个硬编码的包含七个扩展名（exe、cmd、msi、bat、ps1、vbs、reg）的列表。该检查仅对条目扩展名与该列表进行精

Vulnerability Title
Incomplete dangerous-extension list in PeaZip object open allows execution of a program or command from a crafted archive entry without confirmation
来源: CVE Program / CVE List V5
Vulnerability Description
Incomplete List of Disallowed Inputs (CWE-184) in the dangerous-extension confirmation of the archive object viewer (peach.pas, grid_obj_open) in PeaZip 10.5.0 through 11.2.0 on Windows allows an attacker who convinces a victim to open an entry of a crafted archive to execute a program, or an arbitrary command, with no confirmation dialog. The prompt (Do you want to run this file?) is gated by SECEXTCONST, a hard-coded list of seven extensions (exe cmd msi bat ps1 vbs reg); the check is an exact string comparison of the entry extension against that list, so it answers only whether the extension is one of the seven and never whether the shell will execute the file. Shell-executable and scripting-host types that Windows runs through ShellExecuteW are absent from the list, among them .url and .lnk. An archived Windows Internet Shortcut (.url) whose URL line is attacker-controlled is launched with no prompt, while the byte-identical content in an entry named .bat does raise the warning in the same session. A .lnk entry raises the ceiling from launching a program to running a command line, because a Windows shortcut carries arguments: a proof-of-concept shortcut targeting cmd.exe with an attacker-chosen command line executed with no prompt. The shortcut target is not confined to the local disk; the shell also resolved an attacker-named UNC path (fetching a remote payload was only attempted, not demonstrated). No privilege escalation; everything runs as the user who opened the archive.
