Detailsinfo

A vulnerability, which was classified as problematic, was found in horsicq DIE-engine up to 3.20.x. This affects an unknown code of the component Archive Extraction Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-23. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This is going to have an impact on integrity, and availability. The summary by CVE is:

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.

The weakness was shared with Mobasi Security Team. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-43616 since 05/01/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available.
