      <title>CVE-2026-55798 — Pillow: WindowsViewer.get_command() OS command injection via unescaped shell path</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-55798</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; python-pillow Pillow&lt;/p&gt;
&lt;p&gt;Pillow is a Python imaging library. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe shell command by directly embedding a file path into an f-string without escaping and passed the result to subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary cmd.exe commands. This issue is fixed in version 12.3.0.&lt;/p&gt;</description>
