EPSS · scored 2026-10-28

The Express web framework before 3.11 and 4.x before 4.5 for Node.js does not provide a charset field in HTTP Content-Type headers in 400 level responses, which might allow remote attackers to conduct cross-site scripting (XSS) attacks via characters in a non-standard encoding.

advisories (1)

Vendor and ecosystem advisories describing this.

GHSA-gpvr-g6gh-9mc2No Charset in Content-Type Header in express2018-10-23ghsa · osvUS
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.
