actuator/mappings

Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

actuator/mappings

Spring Boot Actuator mappings endpoint exposing all request mappings

What an attacker could do

This endpoint reveals every request mapping in the application, handing attackers a complete map of hidden and undocumented routes, internal APIs, and admin handlers to target next.

How to defend it

Exclude mappings from web exposure, secure the Actuator context behind authentication, and run management endpoints on an internal-only port unreachable from the internet.
