描述
Description
Unlike SQLite3::loadExtension, Pdo\Sqlite::loadExtension does not check sqlite3.extension_dir and calls sqlite3_load_extension with the absolute path to the extension parameter. This allows executing native code from PHP code subject to open_basedir / disable_functions (which are not security boundaries anyway).
I'll open a PR with my patch later this week. It introduces a similar check to SQLite3::loadExtension and restricts extension loading to a trusted directory (sqlite3.extension_dir) set in advance.
