EUVDB-ID: #VU24060

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-2019-17022

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data within the CSS sanitizer. When pasting a tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. If a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability.
