      <title>CVE-2026-39819 — Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-39819</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Go toolchain cmd/go&lt;/p&gt;
&lt;p&gt;The &amp;#34;go bug&amp;#34; command writes to two files with predictable names in the system temporary directory (for example, &amp;#34;/tmp&amp;#34;). An attacker with access to the temporary directory can create a symlink in one of these names, causing &amp;#34;go bug&amp;#34; to overwrite the target of the symlink.&lt;/p&gt;</description>
