Sources and claim methodology

Upstream source 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.
