CVE-2026-32691
Timing ownership claim attack on new external back-end secrets
In short
A race condition in Juju's secrets management allows an authenticated attacker to claim ownership of a newly created secret before it's fully initialized, potentially exposing the secret's content to an unauthorized unit.
Technical detail
A race condition exists in the secrets management subsystem (CWE-708) between secret ID generation and first revision creation in Juju 3.0.0–3.6.18. An authenticated unit agent can exploit this timing window to claim ownership of a known secret, gaining read access to the initial revision's content.
Summary generated and translated by AI from the official description.
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.
