CVE-2025-04117-Zip — extracted files lose their web-origin marking

7-Zip does not carry the marking that tells Windows a file came from the internet through to what it extracts, so a document from a crafted archive opens without the warnings that marking triggers.

YOUR NEXT MOVE

Update 7-Zip to a patched release now; until then treat files extracted from downloaded archives as if they had come straight off the internet.
