Prometheus Perils: Exposed Servers Reveal Passwords and Invite Cyber Mayhem
Prometheus, the popular open source monitoring tool, might be exposing more than just metrics. Researchers found thousands of servers leaking passwords, tokens, and facing DoS risks. On the bright side, if you ever wanted to crash a fighter jet with Kubernetes, now you know a guy! Time to tighten those security belts.

Hot Take:
Looks like Prometheus is pulling a “Pandora’s Box” stunt, opening the door to hackers with a generous serving of plaintext passwords, juicy tokens, and a side order of DoS attacks. Who knew server monitoring could be so… revealing? Maybe it’s time for users to play hide and seek with their data instead of peekaboo!
Key Points:
- Over 40,000 Prometheus servers and 296,000 exporters are exposed on the open Web.
- Exposed data includes plaintext passwords, tokens, and sensitive API addresses.
- Open Prometheus servers can be exploited for DoS attacks through ‘/debug/pprof’ endpoints.
- Repojacking vulnerabilities found in several Prometheus exporters.
- Prometheus documentation has been updated to address repojacking risks.
