CVE-2026-73245Public exploitNetwork attack vectorHinoki check available

Configuration disclosure and logging changes via management endpoints

Published Aug 11, 2026 · Updated Aug 11, 2026

Missing authentication in Kestra before 2.0.0-rc6 allows remote attackers to read configuration and alter runtime logging via port 8081. The shipped application.yml serves Micronaut /env and /loggers routes on a separate listener outside the API Basic Auth filter. Any network client that can reach port 8081 can retrieve resolved property sources and change logger levels without credentials; credential values remain masked.
