NLTK: Allowlisted pickle loaders still permit code execution in current source

Summary The current source tree still allows arbitrary code execution during supposedly safer allowlisted pickle loading. The allowlist trusts whole module namespaces instead of exact safe globals, so crafted pickles can invoke dangerous in-namespace callables through pickle REDUCE. Details -...

NLTK: Entity-expansion DoS (billion laughs) via remaining raw ElementTree parses

Several XML parsing sites in NLTK still used xml.etree.ElementTree directly, which honours declarations in a document's internal DTD subset. A crafted document a few hundred bytes long can expand to megabytes in memory each nesting level multiplies by ten, a denial-of-service. Affected call sites...

NLTK: pathsec SSRF protection can be bypassed when a proxy is configured

Summary Current NLTK source reopens SSRF in proxied environments. pathsec.urlopen validates the requested hostname locally, but once proxy inheritance is enabled the real fetch is performed by the proxy rather than by the validated direct-connect socket path. Details - Vulnerability type:...

NLTK: StreamBackedCorpusView Bypasses pathsec.ENFORCE - Arbitrary Local File Read

Summary Setting nltk.pathsec.ENFORCE = True is documented to sandbox all file access to allowed NLTK data directories and raise PermissionError on unauthorized access. However, StreamBackedCorpusView opens files via builtins.open directly, bypassing pathsec.validatepath entirely. An attacker who...

NLTK: FileSystemPathPointer.open() sandbox check is dead code — arbitrary file read via file:// protocol

Summary There's a logic bug in FileSystemPathPointer.open inside nltk/data.py that makes the sandbox check permanently inert. The guard condition is always False — meaning any file the process can read is accessible by passing a file:// URL to nltk.data.load. --- Details In nltk/data.py,...

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...
