      <title>CVE-2026-18447 — PostgreSQL output parameter type confusion executes arbitrary code</title>
      <link>https://db.gcve.eu/vuln/cve-2026-18447</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; PostgreSQL&lt;/p&gt;
&lt;p&gt;Type confusion in PostgreSQL SQL-language functions allows an object creator to execute arbitrary code as the operating system user running the database, via an output parameter of type &amp;#34;any&amp;#34;.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.&lt;/p&gt;</description>
