Webhook Security Misconfiguration
1-minute read
What it is
Webhook Security Misconfiguration occurs when webhook endpoints lack authentication, validation, or access controls, allowing anyone to send crafted callbacks.
Why it matters
Attackers can inject false events, leak data, or disrupt integrations by impersonating trusted services.
How to reduce risk
- Validate webhook signatures or shared secrets on every request
- Restrict allowed sources and IP ranges for webhook traffic
- Log webhook attempts and alert on suspicious patterns
