NLTK: Symlink escape in CorpusReader allows arbitrary local file read outside the corpus root

Summary nltk.corpus.reader.api.CorpusReader.open can be used to read files outside the intended corpus root via a symlink placed inside that root. Although NLTK blocks absolute paths and .. traversal, the current boundary check is only lexical and does not account for symlink resolution. This lea...

SUSE CVE-2026-70626

NLTK versions before 3.9.4 contain a symlink escape vulnerability in CorpusReader.open that allows local attackers to read arbitrary files outside the corpus root. The vulnerability exists because path validation is lexical and does not account for symlink resolution, enabling attackers to place...

CVE-2026-70626

A flaw was found in NLTK. This vulnerability allows a local attacker to read arbitrary files outside of the intended directory. By placing symbolic links symlinks within the corpus root, an attacker can bypass path validation in the CorpusReader.open function, which does not properly account for...

CVE-2026-70626

NLTK versions before 3.9.4 are affected by a symlink escape vulnerability in CorpusReader.open() . The root cause is that path validation is purely lexical and does not resolve symlinks, allowing a local attacker to place a symlink inside the corpus root to read arbitrary files outside the intend...

PT-2026-79569

Name of the Vulnerable Software and Affected Versions NLTK versions prior to 3.9.4 Description A symlink escape issue exists in the CorpusReader.open function. This occurs because path validation is performed lexically and fails to account for symlink resolution. Consequently, a local attacker ca...
