Summary
No Charset in Content-Type Header in express
Details

Vulnerable versions of express do not specify a charset field in the content-type header while displaying 400 level response messages. The lack of enforcing user's browser to set correct charset, could be leveraged by an attacker to perform a cross-site scripting attack, using non-standard encodings, like UTF-7.

Recommendation

For express 3.x, update express to version 3.11 or later. For express 4.x, update express to version 4.5 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
