GHSA-XH95-F55M-82FW Natural Language Toolkit (NLTK) has path traversal in FramenetCorpusReader.frame() that allows arbitrary XML file read, bypassing the nltk.pathsec sandbox (ENFORCE=True)

Summary FramenetCorpusReader.framename interpolates a caller-supplied frame name into an XML file path that is read with the builtin open, bypassing CorpusReader.open and the nltk.pathsec sandbox — including strict ENFORCE=True mode. A ../ sequence in the name escapes the corpus root, yielding an...
