01

Who is affected

Users of Mistral Vibe, regardless of version, are affected because the product’s command handling does not properly validate quoted arguments.

Real-world impact

An attacker could take full control of a victim’s machine, install malware, exfiltrate data, or use the system as part of a larger attack chain, all without needing any user interaction.

03

Why this severity

The CVSS score of 10 reflects that the flaw is exploitable remotely, requires no authentication, and gives an attacker complete control over the affected system. All impact metrics (confidentiality, integrity, availability) are rated high, and the attack vector is network‑based.
