2) Universal cross-site scripting
EUVDB-ID: #VU29049
Risk: Medium
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-6506
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the Google Chrome WebView system component. The vulnerability allows cross-origin iframes to execute arbitrary JavaScript in the top-level document.
