Compute CISA SSVC (Stakeholder-Specific Vulnerability Categorization) for a CVE. ## What this tool does Calculates the SSVC decision (Track, Track*, Attend, Act) using: - exploitation status - technical impact - automatable exploitation - mission prevalence (user-provided) - public well-being impact (user-provided) This reflects CISA's official SSVC prioritization model. ## When to use this tool Use this tool when the user asks about: - how urgently a CVE should be remediated - CISA SSVC priority or risk category - a structured decision model for remediation ## Inputs - **cve_id**: the vulnerability to evaluate (`CVE-YYYY-NNNNN`) - **mission_prevalence**: `M`, `S`, or `E` (must be provided by the user) - **public_well_being_impact**: `M`, `A`, or `I` (must be provided by the user) ## Outputs - `decision`: one of **Track**, **Track\***, **Attend**, **Act** - `exploitation` - `technical_impact` - `automatable` - `mission_prevalence` - `public_well_being_impact` - `mission_and_well_being_impact_value` - `vector_string` - `summary`: Markdown explanation of the outcome ## LLM usage guidelines - Always ask the user for **mission_prevalence** (M/S/E) and **public_well_being_impact** (M/A/I) before calling. - Never guess these values—SSVC depends on user context. - Use the `summary` to explain clearly why the decision was returned. - Combine with `vulnerability_score` or `sightings_search` if the user needs additional context.
