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?
api/v1/timescaledb/metrics
TimescaleDB Metrics API
What an attacker could do
As a PostgreSQL extension, an exposed TimescaleDB endpoint inherits Postgres risk: with weak or default credentials an attacker reads hypertables of time-series data and can leverage SQL functions or COPY to access the host filesystem.
How to defend it
Enforce strong PostgreSQL role passwords and pg_hba.conf host restrictions, require TLS connections, and never expose port 5432 or any metrics proxy directly to the internet.
