Summary
Cross-Site Scripting in sanitize-html
Details

Affected versions of sanitize-html are vulnerable to cross-site scripting.

Proof of Concept:

<IMG SRC= onmouseover="alert('XSS');"> produces the following:

<img src="onmouseover="alert('XSS');"" /> This is definitely invalid HTML, but would suggest that it's being interpreted incorrectly by the parser.

Recommendation

Update to version 1.2.3 or later.

Severity ?
6.1 (Medium)
CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
