CVE-2026-47890

A flaw was found in Spring Framework, affecting its MVC and WebFlux applications. When these applications use Server-Sent Events SSE with view fragments, a vulnerability allows for stream corruption. This can lead to unreliable data delivery and potential disruption of services. Mitigation Disabl...

CVE-2026-61593 djust has Cross-Site Request Forgery on the Server-Sent-Events transport: a cross-origin page can drive a victim-authenticated SSE session

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the SSE client→server POST endpoints are @csrfexempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a...

CVE-2026-84378

A flaw was found in httpx2, a Python HTTP client. The Server-Sent Events SSE parser in httpx2 can be exploited by a remote attacker. By sending a specially crafted stream where an unterminated line is split across many response chunks, the parser repeatedly copies and rescans buffered text. This...
