🧮 Severity Anatomy — CVSS 3.1 vector, decoded from the primary record

The base score summarizes severity in one number; the vector explains why. Each row below is a direct read of the official CVSS vector — verifiable against the NVD record.

Metric	Value	What it means for defenders
Attack Vector	Local `AV:L`	Requires local access — a shell, session, or local file/app interaction.
Attack Complexity	Low `AC:L`	No special conditions — reliably repeatable by an attacker.
Privileges Required	None `PR:N`	No authentication needed — pre-auth exploitation.
User Interaction	Required `UI:R`	A user must click, open, or visit something — social engineering component.
Scope	Changed `S:C`	Impact extends beyond the vulnerable component — can affect other systems/security domains.
Confidentiality Impact	High `C:H`	Total loss of confidentiality — full data disclosure possible.
Integrity Impact	High `I:H`	Total loss of integrity — attacker can modify any data.
Availability Impact	High `A:H`	Total loss of availability — full denial of service possible.

⚠️ Business Impact Analysis

⚠️ Remote code execution — full server takeover without authentication possible
