Api Scraping in Buffalo

API scraping in Buffalo applications typically emerges from three core patterns: insecure direct object references (IDOR/BOLA), excessive data exposure, and missing rate limiting. Buffalo's convention-over-configuration approach can inadvertently expose attack surfaces if developers rely too heavily on default behaviors without explicit authorization checks.

IDOR via Unchecked Resource Access
Buffalo actions frequently use dynamic route parameters like :id to fetch records. Without proper ownership validation, attackers can systematically enumerate these IDs to scrape all resources. Consider this vulnerable user profile endpoint:

// actions/users.go
func UserShow(c buffalo.Context) error {
    user := &models.User{}
    // Vulnerable: No check that current user owns this resource
    if err := c.Param(
