Insufficient Policy Enforcement in Extensions in Google Chrome prior to 62.0.3202.62 allowed a remote attacker to perform domain spoofing in permission dialogs via IDN homographs in a crafted Chrome Extension.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N
- Base score: 6.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 1.85%
- Percentile among all scored CVEs: 79
- Score date: 10/18/2026
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).
💥 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.
