Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Kestra versions before 2.0.0 expose Micronaut management endpoints on port 8081 without authentication, even when basic-auth is enabled on the main API port 8080. An attacker who can reach port 8081 over the network can read the resolved environment and configuration through the /env endpoint and change runtime log levels through /loggers, with credential values masked. The source lists no workaround; the fix is to upgrade to version 2.0.0. Until then, restrict network access to port 8081 so it is not reachable from untrusted networks.
