      <title>GHSA-4m7w-qmgq-4wj5 — aiohttp: TLS Server Hostname Override Is Ignored When Reusing HTTPS Connections</title>
      <link>https://db.gcve.eu/vuln/ghsa-4m7w-qmgq-4wj5</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; PyPI: aiohttp&lt;/p&gt;
&lt;p&gt;### Summary&lt;/p&gt;
&lt;p&gt;The `server_hostname` TLS SNI check can be bypassed when an existing connection is reused.&lt;/p&gt;
&lt;p&gt;### Impact&lt;/p&gt;
&lt;p&gt;If an application makes multiple requests to the same domain, but with different per-request `server_hostname` parameters, then the later calls may succeed by reusing the existing connection when they should have been rejected due to the TLS SNI check.&lt;/p&gt;
&lt;p&gt;### Workaround&lt;/p&gt;
&lt;p&gt;Disable keep_alive if you need to change the `server_hostname` check between requests.&lt;/p&gt;
&lt;p&gt;-----&lt;/p&gt;
&lt;p&gt;Patch: https://github.com/aio-libs/aiohttp/commit/0ca2b6c28a25726527a8b60f25960262a91ed0e0&lt;/p&gt;</description>
