Kerentanan Improper Neutralization of CRLF Sequences ('CRLF Injection') pada rexxars eventsource-encoder. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

eventsource-encoder encodes events as well-formed EventSource/Server Sent Event (SSE) messages. Prior to 1.0.2, eventsource-encoder does not sanitize the event or id fields of an EventSourceMessage before serializing them. An attacker who controls either field can inject arbitrary Server-Sent Events line terminators (\n, \r, or \r\n) and thereby forge additional SSE fields or entire messages on the stream. This vulnerability is fixed in 1.0.2.
