metadata_generator.py#202Conversation
This commit adds a defense-in-depth enhancement to `_migrate_database_schema` in `metadata_generator.py`. The `ALTER TABLE` DDL statement uses an f-string to insert column names. By validating the column name with `str.isidentifier()`, we ensure that it is a safe SQL column name, preventing SQL injection if the column configuration is ever exposed to user input.

This PR implements a security enhancement to prevent potential SQL injection.
Vulnerability:
The
_migrate_database_schemamethod inmetadata_generator.pydynamically buildsALTER TABLEstatements using an f-string to insert the column name. Although the dictionary keys are currently hardcoded, if they ever become user-controlled, this would introduce an SQL injection vulnerability because SQL column names cannot be parameterized with?.Fix:
Added a check using Python's
str.isidentifier()to validate that the column name conforms to safe syntax (alphanumeric and underscores) before executing the query. If the validation fails, aValueErroris raised.Impact:
Increases defense-in-depth and ensures the database migration mechanism remains secure even if the schema configuration method changes in the future.
