    CVE-2026-44214 (GCVE-0-2026-44214)

    Vulnerability from cvelistv5 – Published: 2026-05-26 19:34 – Updated: 2026-05-27 13:19

    Title
    eventsource-encoder: SSE event injection via unsanitized event and id fields
    Summary
    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.

    Title
    sse-channel: SSE Injection via unsanitized event fields
    Summary
    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 the stream. This vulnerability is fixed in 4.0.1.
