CVE-2026-43616
Detect-It-Easy prior to 3.21 contains a path traversal vulnerability that allows attackers to write arbitrary files to the filesystem by crafting malicious archive entries with relative traversal sequences or absolute paths. Attackers can exploit insufficient path normalization during archive extraction to write files outside the intended extraction directory and achieve persistent code execution by overwriting user startup scripts.
View on NVDAnalysis
Detect-It-Easy (DIE) versions prior to 3.21 are vulnerable to a path traversal attack during archive extraction. An attacker can craft a malicious file that, when analyzed, writes arbitrary files to your system, potentially overwriting startup scripts to achieve persistent code execution. Developers and researchers using this tool to inspect binaries should update to version 3.21 immediately.
