CVE-2019-0678
Status: ModifiedMedium (6.8)—💥 PoC
An elevation of privilege vulnerability exists when Microsoft Edge does not properly enforce cross-domain policies, which could allow an attacker to access information from one domain and inject it into another domain.In a web-based attack scenario, an attacker could host a website that is used to attempt to exploit the vulnerability, aka 'Microsoft Edge Elevation of Privilege Vulnerability'.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N
- Base score: 6.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 6.09%
- Percentile among all scored CVEs: 93
- Score date: 10/9/2026
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.
