      <title>CVE-2026-81726 — NLTK through 3.10.3 Path Traversal via Model-Artifact APIs</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-81726</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nltk&lt;/p&gt;
&lt;p&gt;NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled.&lt;/p&gt;</description>
