CVE-2020-8287
Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP request (for example, two Transfer-Encoding header fields).
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 16.3%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
Description
Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling.
