CVE-2026-32691 (GCVE-0-2026-32691)

Vulnerability from cvelistv5 – Published: 2026-03-18 12:28 – Updated: 2026-03-18 13:49

Title

Timing ownership claim attack on new external back-end secrets

Summary

A race condition in the secrets management subsystem of Juju versions 3.0.0 through 3.6.18 allows an authenticated unit agent to claim ownership of a newly initialized secret. Between generating a Juju Secret ID and creating the secret's first revision, an attacker authenticated as another unit agent can claim ownership of a known secret. This leads to the attacking unit being able to read the content of the initial secret revision.

Severity

Vulnerability from github – Published: 2026-03-19 12:42 – Updated: 2026-03-19 12:42

Summary

Juju affected by timing ownership claim attack on new external back-end secrets

Details

Impact

Between generating a Secret ID and creating the secret's first revision, an attacker authenticated as another unit agent can claim ownership of a known secret. This leads to the attacking unit being able to read the content of the initial secret revision.
