Update now: 7-Zip fixes RCE flaw exploitable with malicious archives

7-Zip 26.02 addresses a remote code execution flaw that can be triggered through malicious compressed files opened by a user. The risk is higher in environments where archives arrive through email, chat, ticketing systems, or file-sharing workflows.

Why it matters: Prioritize updating 7-Zip on endpoints and servers, and reinforce controls that scan, sandbox, or quarantine untrusted archives before users open them.
