    CISA KEV: Fortinet FortiOS CVE-2025-68686 (CVSS 3.1 5.9 MEDIUM) - FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability

    An Exposure of Sensitive Information to an Unauthorized Actor vulnerability [CWE-200] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.1, FortiOS 7.4.0 through 7.4.6, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiOS 6.4 all versions may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.

    How we got to 8.2

    1. 1
      CVSS technical severity (40%)

      Industry-standard exploitability + impact score. We prefer CVSS 4.0 and fall back to 3.1 per the FDA's Feb 2026 premarket cybersecurity guidance. Missing CVSS scores get a neutral 4.0 so unknown vulns are not over- or under-rated.

      3.1 base 5.9 × 40% = +2.36
    2. 2
      Patient safety impact (35%)

      What happens to a patient if this vuln is exploited on a connected device. Auto-inferred from headline, dek, tags, and device class against a curated MedTech keyword library (pacemaker, infusion pump, EHR, PACS, etc.).

      Life-threatening → 10 × 35% = +3.50
    3. 3
      Exploit maturity (15%)

      Is anyone actually using this in attacks? KEV listing > weaponized exploit > public PoC > none. KEV alone forces tier=critical regardless of CVSS.

      On CISA KEV (in-the-wild) → 10 × 15% = +1.50
    4. 4
      MedTech exposure (10%)

      How likely this affects clinical operations: presence in our MedTech feed (+4 baseline), network-reachable signals (+3), known device-class tags (+2), identified MedTech vendor (+1).

      Exposure 8/10 × 10% = +0.80

    Tier cutoffs: Critical ≥ 8.5 · High 7.0–8.4 · Notable 4.0–6.9 · Info < 4.0. Full methodology, weights, and changelog at /goatfeed/risk-rubric.
