The _unzip_iter function in nltk/downloader.py uses zipfile.extractall() without performing path validation or security checks. This allows attackers to craft malicious zip packages that, when downloaded and extracted by NLTK, can execute arbitrary code. The vulnerability arises because NLTK assumes all downloaded packages are trusted and extracts them without validation. If a malicious package contains Python files, such as __init__.py, these files are executed automatically upon import, leading to remote code execution. This issue can result in full system compromise, including file system access, network access, and potential persistence mechanisms.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2025-14009","url":"https://www.suse.com/security/cve/CVE-2025-14009"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1258436 for CVE-2025-14009","url":"https://bugzilla.suse.com/1258436"}],"title":"SUSE CVE CVE-2025-14009","tracking":{"current_release_date":"2026-02-23T00:26:00Z","generator":{"date":"2026-02-23T00:26:00Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-14009","initial_release_date":"2026-02-23T00:26:00Z","revision_history":[{"date":"2026-02-23T00:26:00Z","number":"2","summary":"vulnerabilities added,references added,severity changed from  to moderate"}],"status":"interim","version":"2"}},"product_tree":{"branches":[{"branches":[{"branches":[{"category":"product_name","name":"SUSE Package Hub 15 SP6","product":{"name":"SUSE Package Hub 15 SP6","product_id":"SUSE Package Hub 15 SP6"}},{"category":"product_name","name":"openSUSE Leap 15.6","product":{"name":"openSUSE Leap 15.6","product_id":"openSUSE Leap 15.6","product_identification_helper":{"cpe":"cpe:/o:opensuse:leap:15.6"}}},{"category":"product_name","name":"openSUSE Tumbleweed","product":{"name":"openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed","product_identification_helper":{"cpe":"cpe:/o:opensuse:tumbleweed"}}},{"category":"product_version","name":"python3-nltk-3.7-bp156.4.6.1","product":{"name":"python3-nltk-3.7-bp156.4.6.1","product_id":"python3-nltk-3.7-bp156.4.6.1","product_identification_helper":{"purl":"pkg:rpm/suse/python3-nltk@3.7-bp156.4.6.1"}}},{"category":"product_version","name":"python311-nltk-3.9.1-3.1","product":{"name":"python311-nltk-3.9.1-3.1","product_id":"python311-nltk-3.9.1-3.1","product_identification_helper":{"purl":"pkg:rpm/suse/python311-nltk@3.9.1-3.1"}}},{"category":"product_version","name":"python312-nltk-3.9.1-3.1","product":{"name":"python312-nltk-3.9.1-3.1","product_id":"python312-nltk-3.9.1-3.1","product_identification_helper":{"purl":"pkg:rpm/suse/python312-nltk@3.9.1-3.1"}}},{"category":"product_version","name":"python313-nltk-3.9.1-3.1","product":{"name":"python313-nltk-3.9.1-3.1","product_id":"python313-nltk-3.9.1-3.1","product_identification_helper":{"purl":"pkg:rpm/suse/python313-nltk@3.9.1-3.1"}}}],"category":"product_family","name":"SUSE Linux Enterprise"}],"category":"vendor","name":"SUSE"}],"relationships":[{"category":"default_component_of","full_product_name":{"name":"python3-nltk-3.7-bp156.4.6.1 as component of SUSE Package Hub 15 SP6","product_id":"SUSE Package Hub 15 SP6:python3-nltk-3.7-bp156.4.6.1"},"product_reference":"python3-nltk-3.7-bp156.4.6.1","relates_to_product_reference":"SUSE Package Hub 15 SP6"},{"category":"default_component_of","full_product_name":{"name":"python3-nltk-3.7-bp156.4.6.1 as component of openSUSE Leap 15.6","product_id":"openSUSE Leap 15.6:python3-nltk-3.7-bp156.4.6.1"},"product_reference":"python3-nltk-3.7-bp156.4.6.1","relates_to_product_reference":"openSUSE Leap 15.6"},{"category":"default_component_of","full_product_name":{"name":"python311-nltk-3.9.1-3.1 as component of openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed:python311-nltk-3.9.1-3.1"},"product_reference":"python311-nltk-3.9.1-3.1","relates_to_product_reference":"openSUSE Tumbleweed"},{"category":"default_component_of","full_product_name":{"name":"python312-nltk-3.9.1-3.1 as component of openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed:python312-nltk-3.9.1-3.1"},"product_reference":"python312-nltk-3.9.1-3.1","relates_to_product_reference":"openSUSE Tumbleweed"},{"category":"default_component_of","full_product_name":{"name":"python313-nltk-3.9.1-3.1 as component of openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed:python313-nltk-3.9.1-3.1"},"product_reference":"python313-nltk-3.9.1-3.1","relates_to_product_reference":"openSUSE Tumbleweed"}]},"vulnerabilities":[{"cve":"CVE-2025-14009","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2025-14009"}],"notes":[{"category":"general","text":"A critical vulnerability exists in the NLTK downloader component of nltk/nltk, affecting all versions.
