CVE-2026-71514
2.5 · LOWOverview
CVE-2026-71514 is a low-severity vulnerability. It was published on August 22, 2026 and has a CVSS 3.1 base score of 2.5 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.5, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
