An attacker can bypass protections by URL-encoding traversal sequences (for example, %2fetc%2fpasswd instead of /etc/passwd) and read arbitrary files from the filesystem.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-p4gq-832x-fm9v","publishedAt":"2026-06-16T14:34:15.000Z","cveId":"CVE-2026-54293","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["nltk@<= 3.9.4"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["NLTK","Natural Language Toolkit"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-06-16T14:34:15.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010"]}}
