I mean, just writing to ~/.bash_profile wont work as i assume it needs to be executable. (I assume it wont work if the file already exists since it expects to be a valid db if it exists). In practise, finding an actual path to write to that actually gets code to execute might be tricky in the context of a unix user used just for one specific sqlite backed service. Sqlite also has an option to disable the attach keyword (SQLITE_LIMIT_ATTACHED). It is very rare to get sql injection at the beginning of the query so in practise this usually isn't an issue (although i guess that was your point).
