{"id":"GHSA-8vh5-mgjj-w6hg","summary":"Duplicate Advisory: [CWE-1188] Default ENFORCE=False Disables All pathsec Security Controls","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-p3m8-78j2-g5p3. This link is maintained to preserve external references.\n\n## Original Description\nNLTK versions before 3.10.0 default to ENFORCE=False in pathsec.py, causing all security validation functions to emit warnings instead of raising exceptions. Attackers can bypass path traversal and pickle deserialization protections by exploiting the disabled security controls that are only active when manually enabled.","modified":"2026-09-02T16:00:17.573915906Z","published":"2026-08-22T15:31:03Z","withdrawn":"2026-09-02T15:40:08Z","database_specific":{"github_reviewed_at":"2026-09-02T15:40:08Z","nvd_published_at":"2026-08-22T15:16:18Z","cwe_ids":["CWE-1188"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/nltk/nltk/security/advisories/GHSA-p3m8-78j2-g5p3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62388"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/nltk-before-insecure-default-configuration-pathsec"}],"affected":[{"package":{"name":"nltk","ecosystem":"PyPI","purl":"pkg:pypi/nltk"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.9.4"}]}],"versions":["0.8","0.9","0.9.3","0.9.4","0.9.5","0.9.6","0.9.7","0.9.8","0.9.9","2.0.1","2.0.1rc1","2.0.1rc2-git","2.0.1rc3","2.0.1rc4","2.0.2","2.0.3","2.0.4","2.0.5","2.0b4","2.0b5","2.0b6","2.0b7","2.0b8","2.0b9","3.0.0","3.0.0b1","3.0.0b2","3.0.1","3.0.2","3.0.3","3.0.4","3.0.5","3.1","3.2","3.2.1","3.2.2","3.2.3","3.2.4","3.2.5","3.3","3.4","3.4.1","3.4.2","3.4.3","3.4.4","3.4.5","3.5","3.5b1","3.6","3.6.1","3.6.2","3.6.3","3.6.4","3.6.5","3.6.6","3.6.7","3.7","3.8","3.8.1","3.9","3.9.1","3.9.2","3.9.3","3.9.4","3.9b1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-8vh5-mgjj-w6hg/GHSA-8vh5-mgjj-w6hg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
