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 can place symlinks within the corpus root to read arbitrary files located outside the intended boundary.Recommendations
Update to version 3.9.4 or later.
