<p>There are no known security issues with sharing the same PSK between TLSv1.2 (or below) and TLSv1.3. However, the RFC has this note of caution:</p>

<p>&quot;While there is no known way in which the same PSK might produce related output in both versions, only limited analysis has been done. Implementations can ensure safety from cross-protocol related output by not reusing PSKs between TLS 1.3 and TLS 1.2.&quot;</p>
