+  "summary": "sniff_csv provides filesystem access even when enable_external_access is disabled in duckdb",
+  "details": "### Summary\nContent in filesystem is accessible for reading using `sniff_csv`, even with `enable_external_access=false`. \n\n### Details\nDuring a pentest, a security researcher was able to access environment variable data and other system data by using the `sniff_csv` function, even though we set `enable_external_access` to false. \n\n### PoC\n```SQL\nSET enable_external_access=false;\nSET lock_configuration=true;\n\nSELECT Columns FROM sniff_csv('/proc/self/environ');\n```\n\n### Impact\nProvides an attacker with access to filesystem even when access is expected to be disabled and other similar functions do NOT provide access. \n\nFor example `select * from read_csv('/proc/self/environ')` fails with a permission error. \n\nThere seems to be two vectors to this vulnerability: \n1. 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",
