CVE-2026-63312

NLTK before 3.10.0 contains an arbitrary local file read vulnerability in StreamBackedCorpusView . The root cause is that the component calls builtins.open() directly instead of the sandboxed pathsec.open() , effectively bypassing the pathsec.ENFORCE security mechanism. An attacker who controls t...

CVE-2026-63312 NLTK StreamBackedCorpusView Bypasses pathsec.ENFORCE Arbitrary File Read

NLTK before 3.10.0 contains an arbitrary local file read vulnerability in StreamBackedCorpusView that bypasses pathsec.ENFORCE by calling builtins.open directly instead of pathsec.open. Attackers who control the fileid argument can read arbitrary local files regardless of the ENFORCE setting,...

CVE-2026-62383

nltk versions before 3.10.2 contain a symlink-based arbitrary file read vulnerability in the IPIPANCorpusReader component. The root cause is a complete bypass of nltk.pathsec validation: an attacker with local access can place a symlink in the corpus root directory and invoke channels(), domains(...

CVE-2026-71514 NLTK 3.9.4 through 3.10.2 Path Traversal via CrubadanCorpusReader pathsec Bypass

NLTK 3.9.4 through 3.10.2 contains a path traversal vulnerability in CrubadanCorpusReader. loadlangngrams joins the corpus root with crubadancode, the column-0 value read from the corpus table.txt mapping file, and opens the result with the builtin open rather than the pathsec-validated opener, s...
