CVE-2026-11819

Module: plugins/modules/keyring_info.py 

CVSS 3.1: 5.5 MEDIUM — AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N 

Issue: The module retrieves a passphrase from the OS native keyring (GNOME Keyring, macOS Keychain, Windows Credential Manager) and places it directly into result["passphrase"] with no output suppression, no no_log protection, and no documentation warning. 

Root Cause:

Line 105 (protected): keyring_password=dict(type="str", required=True, no_log=True)
Line 127 (NOT protected): result["passphrase"] = passphrase

Observed Output:

{
"changed": false,
"passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret"
}
Visible via register + debug:
{
"keyring_result": {
"changed": false,
"passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret"
}
}

Impact: 

Master passwords, SSH key passphrases and service credentials appear in all Ansible output 

register: keyring_result followed by debug: var=keyring_result prints passphrase in full 

Ansible fact caching backends (Redis, JSON file, memcached) may persist the passphrase 

AWX/Tower job logs silently store the live credential

Fix:

module.exit_json(changed=False, passphrase=passphrase, _ansible_no_log=True)

Also add a documentation warning requiring callers to use no_log: true at the task level.
