      <title>CVE-2026-44713 — pam_usb: Command injection via $TMUX environment variable leads to RCE as root</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-44713</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; mcdope pam_usb&lt;/p&gt;
&lt;p&gt;pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, src/tmux.c reads the user&amp;#39;s $TMUX environment variable, splits it on commas, and interpolates the socket-path component directly into a shell command passed to popen(). Because the value is placed inside double-quotes without sanitisation, any value containing &amp;#34; terminates the quoted string and injects arbitrary shell syntax. popen() runs as root inside the PAM stack. This vulnerability is fixed in 0.8.7.&lt;/p&gt;</description>
