Not enough EPSS history yet.
nltk versions before 3.10.2 contain a symlink-based arbitrary file read vulnerability in IPIPANCorpusReader methods that bypass nltk.pathsec validation entirely. Attackers can place a symlink in the corpus root directory and read arbitrary files accessible to the process by calling channels(), domains(), categories(), or fileids() methods with the symlink filename.

CVE-2026-76606——
———Joomla Extension - fabrikar.com - Path Traversal via image element in Fabrik < 4.7.3 - ???.7hCVE-2026-76598——
———Joomla Extension - fabrikar.com - Unauthenticated arbitrary directory listing via onAjax_getFolders in Fabrik < 4.7.2 - The onAjax_getFolders method of the elements model allows arbitrary directory listings.7hCVE-2026-633127.5 HIG—
———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, including sensitive system files and application credentials.7hCVE-2026-623847.5 HIG—
———NLTK versions before 3.10.2 contain a symlink-based sandbox bypass in FramenetCorpusReader that allows attackers to read arbitrary XML files outside the corpus root. Attackers can place symlinks with names containing no path separators inside the corpus subdirectory, which pass the path validation guard and are resolved to files outside the intended corpus root when accessed via frame_by_name(), _lu_file(), or doc() methods.7hCVE-2026-715142.5 LOW—
———NLTK 3.9.4 through 3.10.2 contains a path traversal vulnerability in CrubadanCorpusReader. _load_lang_ngrams joins the corpus root with crubadan_code, 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, so os.path.join discards the root when that value is absolute and the read escapes the corpus directory without the containment check nltk.pathsec applies when ENFORCE is set. An attacker who controls a corpus package can disclose file contents outside the corpus root through lang_freq, limited to paths ending in -3grams.txt whose contents parse as token count lines.8hCVE-2026-600848.7 HIG—
———SiYuan versions before v3.7.4 contain an arbitrary file deletion vulnerability in the /api/search/removeTemplate endpoint that accepts an unvalidated path parameter passed directly to os.RemoveAll. Authenticated admin attackers can supply absolute filesystem paths to recursively delete any file or directory the kernel process has permission to remove, anywhere on the host filesystem.9h
