      <title>CVE-2026-20046 — Cisco IOS XR Software CLI Privilege Escalation Vulnerability</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-20046</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Cisco IOS XR Software&lt;/p&gt;
&lt;p&gt;A vulnerability in task group assignment for a specific CLI command in Cisco IOS XR Software could allow an authenticated, local attacker to elevate privileges and gain full administrative control of an affected device.&#13;
&#13;
This vulnerability is due to incorrect mapping of a command to task groups within the source code. An attacker with a low-privileged account could exploit this vulnerability by using the CLI command to bypass the task group&amp;amp;ndash;based checks. A successful exploit could allow the attacker to elevate privileges and perform actions on an affected device without authorization checks.&lt;/p&gt;</description>
