Documents the shift toward 'Exploit-Triggered' remediation SLAs (3-7 days) and validates reachability analysis as a mandatory triage step for federal cloud compliance.
FedRAMP's proposed RFC 0012 (Continuous Vulnerability Management Standard) introduces accelerated remediation deadlines: 3 calendar days for 'Critical' vulnerabilities, 7 days for 'High', 21 days for 'Moderate', and 180 days for 'Low'. Crucially, the standard mandates that any vulnerability with a documented public exploit or active wild exploitation must be reclassified as 'High' or 'Critical' regardless of its original score. To manage this speed, CSPs are required to perform 'credible exploitability analysis' based on function-level reachability and applicability to reduce triage noise. This shift toward FRR-CVM formalizes a move away from static compliance snapshots toward measurable, continuous assurance where exploit status is the primary driver of remediation priority.
RFC 0012 mandates a 3-day fix window for exploitable issues, making upstream remediation velocity the decisive factor for federal compliance.

packages with historically slow remediation cycles cannot satisfy the accelerated SLAs mandated by the FRR-CVM standard, regardless of exploit status.
When a vulnerability is determined to be actively exploited or a public exploit is available, it must be remediated according to the timelines for Critical or High vulnerabilities (3-7 days).
Risk Guard uses static CVSS scores but does not automatically 'Promote' the severity of a vulnerability when a public exploit is discovered.
Risk Guard would be better if it dynamically adjusted its 'Risk Weight' to Critical/High for any package with a documented public exploit.
