CVE-2026-44217 sse-channel: SSE Injection via unsanitized event fields

sse-channel is an SSE-implementation which can be used to any node.js http request/response stream. Prior to 4.0.1, implementations that allow user-provided values to be passed to event, retry or id fields are susceptible to event spoofing, where an attacker could inject arbitrary messages into t...

Cowlib 注入漏洞

Cowlib is a web protocol message parsing and building library developed by Nine Nines. Version 2.6.0 of cowlib contains an injection vulnerability. This vulnerability arises from the program’s failure to properly filter CRLF sequences when processing events sent by the server, resulting in SSE...

CVE-2026-35515

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.18, SseStream.transform interpolates message.type and message.id directly into Server-Sent Events text protocol output without sanitizing newline characters \r, \n. Since the SSE protocol treats both \r and ...
