HIGHCVE-2026-84997

A malformed HTTP message using Transfer-Encoding: chunked can drive React\Http\Io\ChunkedDecoder into an infinite loop, pegging a CPU core and freezing the event loop. Because ReactPHP is single-threaded, one such message stalls the entire process for every client until it is killed.

Affected: >= 0.6.0, <= 1.11.0
Fixed in: 1.11.1
Weakness: CWE-835
