CVE-2026-84378 HTTPX2: Quadratic SSE line buffering can cause CPU denial of service
HTTPX2 is a next generation HTTP client for Python. From 2.5.0 until 2.10.0, the HTTPX2 Server-Sent Events parser in src/httpx2/httpx2/sse.py repeatedly copies and rescans buffered text in SSELineDecoder.decode when an attacker-controlled or compromised SSE endpoint splits one unterminated line...
