Prior to version 0.16.0, a leniency in h11&#39;s parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. This issue has been patched in version 0.16.0. Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue.</p> <p><strong>Affected:</strong> python-hyper h11</p> <p>h11 is a Python implementation of HTTP/1.1.
