CVE-2026-87984: An arbitrary file write vulnerability in Mistral Vibe, introduced in version 1.3.4, allows an attacker to create or over

Mistral Vibe version 1.3.4 has a vulnerability that lets attackers write or overwrite files anywhere on the system without permission. The problem happens because shell redirection (using symbols like > to send output to files) isn't checked for permissions the same way regular commands are, so attackers can bypass security controls.
