CVE:CVE-2026-33128 vulnerable 2026-06-08 07:57:18.703359 h3 has a Server-Sent Events Injection via Unsanitized Newlines in Event Stream Fields
HIGH (7.5)
H3 is a minimal H(TTP) framework. In versions prior to 1.15.6 and between 2.0.0 through 2.0.1-rc.14, createEventStream is vulnerable to Server-Sent Events (SSE) injection due to missing newline sanitization in formatEventStreamMessage() and formatEventStreamComment(). An attacker who controls any part of an SSE message field (id, event, data, or comment) can inject arbitrary SSE events to connected clients. This issue is fixed in versions 1.15.6 and 2.0.1-rc.15.

CVE:CVE-2026-23527 vulnerable 2026-06-08 07:51:15.570466 h3 v1 has Request Smuggling (TE.TE) issue
HIGH (8.9)
H3 is a minimal H(TTP) framework built for high performance and portability. Prior to 1.15.5, there is a critical HTTP Request Smuggling vulnerability. readRawBody is doing a strict case-sensitive check for the Transfer-Encoding header. It explicitly looks for "chunked", but per the RFC, this header should be case-insensitive. This vulnerability is fixed in 1.15.5.
