Status: AnalyzedHigh (8.1)⚠ Active exploitation💥 PoC
Internet Shortcut Files Security Feature Bypass Vulnerability
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
- Base score: 8.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 99%
- Percentile among all scored CVEs: 100
- Score date: 10/6/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
CISA KEV — actively exploited
- Added to catalog: 2/13/2024
- Remediation due date: 3/5/2024
- Known ransomware use: Known
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
- Proof of concept on GitHub (unverified) · List of proofs of concept on GitHub
⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
