Description

In Juju versions prior to 2.9.57 and 3.6.21, an authorization issue exists in the Controller facade. An authenticated user can call the CloudSpec API method to extract the cloud credentials used to bootstrap the controller. This allows a low-privileged user to access sensitive credentials. This issue is resolved in Juju versions 2.9.57 and 3.6.21.

Ghostwire Analysis — What This Means Practically

Exploitation Probability (EPSS): Low — 0.04% (11th percentile)

Low exploitation probability based on current threat landscape data. Standard patching timeline is appropriate.

Critical CVSS score indicates maximum severity — remote code execution, authentication bypass, or complete system compromise is likely possible.
1 proof-of-concept exploit available on GitHub. Public exploit code lowers the barrier for both researchers and attackers.

This analysis is generated by Ghostwire from NVD, CISA KEV, EPSS, and open-source intelligence data. Verify findings through primary sources before acting.
