This is unlikely to occur outside of a contrived scenario.
5.9.1 (March 22, 2026)
Fix: batch result format corruption when using cached prepared statements (reported by Dirkjan Bussink)
5.9.0 (March 21, 2026)
This release includes a number of new features such as SCRAM-SHA-256-PLUS support, OAuth authentication support, and
PostgreSQL protocol 3.2 support.
It significantly reduces the amount of network traffic when using prepared statements (which are used automatically by
default) by avoiding unnecessary Describe Portal messages. This also reduces local memory usage.
It also includes multiple fixes for potential DoS due to panic or OOM if connected to a malicious server that sends
deliberately malformed messages.
Require Go 1.25+
Add SCRAM-SHA-256-PLUS support (Adam Brightwell)
Add OAuth authentication support for PostgreSQL 18 (David Schneider)
Add PostgreSQL protocol 3.2 support (Dirkjan Bussink)

<h1>5.9.2 (April 18, 2026)</h1>
<p>Fix SQL Injection via placeholder confusion with dollar quoted string literals (GHSA-j88v-2chj-qfwx)</p>
<p>SQL injection can occur when:</p>
<ol>
<li>The non-default simple protocol is used.</li>
<li>A dollar quoted string literal is used in the SQL query.</li>
<li>That query contains text that would be would be interpreted outside as a placeholder outside of a string literal.</li>
<li>The value of that placeholder is controllable by the attacker.</li>
</ol>
<p>e.g.</p>
<pre lang="go"><code>attackValue := `$tag$; drop table canary; --`
_, err = tx.Exec(ctx, `select $tag$ $1 $tag$, $1`, pgx.QueryExecModeSimpleProtocol, attackValue)
</code></pre>
