There was a problem hiding this comment.
Removing the error check after Open(cfg) creates a nil pointer dereference vulnerability. If Open() returns an error, client will be nil, but the code continues executing and will crash when attempting to use client in subsequent operations.
Confidence: 5/5
Suggested Fix
| client, err := Open(cfg) | |
| if err != nil { | |
| return nil, err | |
| } | |
| ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second) | |
| func OpenAndMigrate(cfg config.Postgres, migrationsDir string) (*Client, error) { | |
| client, err := Open(cfg) | |
| if err != nil { | |
| return nil, err | |
| } | |
| ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second) | |
| defer cancel() | |
The error check must be restored. The Open() function can fail for various reasons (invalid connection string, database unavailable, etc.), and these errors must be handled before proceeding. Removing this check allows the function to continue with a nil client, which will cause a panic when the client is used.
Prompt for AI
Copy this prompt to your AI IDE to fix this issue locally:
In internal/infra/postgres/postgres.go around line 40, the error check after Open(cfg)
was removed, which creates a nil pointer dereference vulnerability. If Open() returns an
error, the client will be nil but the code continues executing. Restore the error handling
check: if err != nil { return nil, err } immediately after the Open(cfg) call to prevent
crashes when the database connection fails.
📍 This suggestion applies to lines 40-42
