CVE-2026-87723— Untrusted Search Path (PATH Hijacking) in fuse-archive

Quick assessment

Affected
Google fuse-archive
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Google fuse-archive 1.24 之前的版本中，如果攻击者能够向 PATH 环境变量中预置一个目录，或者能够将恶意二进制文件写入到 PATH 中包含的、由攻击者控制或具有写权限的目录，即可劫持执行路径。这使得攻击者可以在运行 fuse-archive 进程的用户安全上下文中执行任意本地代码。该问题在 1.22 版本中得到部分缓解，并在 1.24 版本中通过改进的定向 PATH 过滤机制得到彻底修复。

Vulnerability Title
Untrusted Search Path (PATH Hijacking) in fuse-archive
Source: CVE Program / CVE List V5
Vulnerability Description
In Google fuse-archive versions prior to 1.24, an attacker who can prepend a directory to PATH or write a malicious binary to an attacker-controlled or writable directory appearing in PATH can hijack the execution pathway. This allows the attacker to execute arbitrary local code under the security context of the user running the fuse-archive process. The issue was partially mitigated in version 1.22 and fully resolved in 1.24 via refined selective PATH filtering.
