TL;DR: AI-accelerated development and API-first architectures are widening web application risk in 2025, with StackHawk highlighting broken access control, injection, misconfiguration, and authentication failures alongside emerging prompt injection and SSRF threats. The real issue is not just finding more flaws, but governing faster-changing application and identity boundaries before they are exploited.

Questions worth separating out
Q: How should security teams implement API authentication without creating brittle access controls?
A: Use short-lived credentials, strong token validation, and clear scoping so each API call is tied to a narrow trust boundary.
Q: Why do prompt injection attacks create governance risk for AI agents?
A: Prompt injection creates governance risk because the model often sits in the control path between text input and tool execution.
Q: What do organisations get wrong about secrets in web applications?
A: They often treat secrets as a deployment problem instead of a lifecycle problem.
Practitioner guidance
- Enforce object-level authorization on every API route Map each sensitive endpoint to the exact user, service, and object context it may access.
- Separate model input from tool authority Treat prompts, retrieved documents, and agent instructions as untrusted input.
- Rotate and scope secrets as lifecycle assets Inventory API keys, tokens, certificates, and service credentials across code, CI/CD, logs, and runtime.

Broken access control and prompt injection: are your controls keeping up?
Explore further
Broken access control is now an identity governance problem, not just an application flaw. When APIs and microservices carry business-critical actions, authorisation becomes the real control plane. Session management, object-level access checks, and token scope design determine whether a user or service can reach data it should never see. Practitioners should treat access control failures as identity boundary failures, not only as code defects.
A question worth separating out:
Q: How do security teams know if business application controls are working?
A: Look for three signals: fewer standing exceptions, cleaner SoD outcomes after role combination tests, and access review results that consistently remove unused permissions. If the same people keep receiving broad access across projects or system changes, the control model is drifting. Effective governance should narrow access over time, not accumulate it.
