It seems that it is not possible to enter attribute data for a new vector feature that is not valid SQL due to code being unable to pass user text to the database as text.
Steps to reproduce:
- Create a new vector data set;
- Create a new text attribute column for it;
- Digitize a new feature;
- Provide following text as the attribute value: '; drop database important_data; '
- Observe kaBOOM! as text is parsed by database instead of being properly escaped/passed as prepared statement to the DB.

The issue will work also with more harmless examples like: It's fun
For better effect enter value as: '); delete from MYVECTORMAP; select '
