Access to files that should otherwise not be allowed. (We expect `Permission Error: Scanning CSV files is disabled through configuration` and not to provide any access to the file or even acknowledge that it exists). \n2. The content from a (non-csv?) file can be read (e.g. `/etc/hosts`, `proc/self/environ`, etc) even though that doesn't seem to be the intent of the sniff_csv function (my understanding is it's intending to provide information about the shape of the data, but not provide the data itself). \n\n### Workaround\nIt is possible to work around the issue by disabling the local file system using the `disabled_filesystems` setting:\n```SQL\nSET disabled_filesystems='LocalFileSystem';\nSET lock_configuration=true;\n\nSELECT Columns FROM sniff_csv('/proc/self/environ');\n```\n\nwill result in `Permission Error: File system LocalFileSystem has been disabled by configuration`.\n\n### Fix\nA fix has been merged into the `main` branch (https://github.com/duckdb/duckdb/pull/13133), and will be released with the next DuckDB release.\n\n", + "severity": [ + { + "type": "CVSS_V3", + "score": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N" + } + ], + "affected": [ + { + "package": { + "ecosystem": "PyPI", + "name": "duckdb" + }, + "ranges": [ + { + "type": "ECOSYSTEM", + "events": [ + { + "introduced": "1.0.0" + }, + { + "fixed": "1.1.0" + } + ] + } + ] + } + ], + "references": [ + { + "type": "WEB", + "url": "https://github.com/duckdb/duckdb/security/advisories/GHSA-w2gf-jxc9-pf2q" + }, + { + "type": "ADVISORY", + "url": "https://nvd.nist.gov/vuln/detail/CVE-2024-41672" + }, + { + "type": "WEB", + "url": "https://github.com/duckdb/duckdb/pull/13133" + }, + { + "type": "WEB", + "url": "https://github.com/duckdb/duckdb/commit/c9b7c98aa0e1cd7363fe8bb8543a95f38e980d8a" + }, + { + "type": "PACKAGE", + "url": "https://github.com/duckdb/duckdb" + }, + { + "type": "WEB", + "url": "https://github.com/pypa/advisory-database/tree/main/vulns/duckdb/PYSEC-2024-203.yaml" + } + ], + "database_specific": { + "cwe_ids": [ + "CWE-200" + ], + "severity": "HIGH", + "github_reviewed": true, + "github_reviewed_at": "2025-01-21T21:07:56Z", + "nvd_published_at": "2024-07-24T18:15:05Z" + } +} \ No newline at end of file
