CVE-2026-62383Source published Source updated
nltk versions before 3.10.2 contain a symlink-based arbitrary file read vulnerability in IPIPANCorpusReader methods that bypass nltk.pathsec validation entirely. Attackers can place a symlink in the corpus root directory and read arbitrary files accessible to the process by calling channels(), domains(), categories(), or fileids() methods with the symlink filename. A flaw was found in nltk. A local attacker can exploit a symlink-based vulnerability in the IPIPANCorpusReader methods. By placing a symbolic link in the corpus root directory and invoking specific methods, an attacker can bypass security validation and read arbitrary files accessible to the process. This could lead to unauthorized information disclosure. The `nltk` library is vulnerable to information disclosure, allowing an…
