Ansible keyring_info leak passphrase via no_log omission
CVE-2026-11819 Published on June 23, 2026
Community.general: community.general keyring_info — os keyring passphrase returned in plaintext
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.
PoCs

Fig 2: Source code showing no_log=True on input (line 105) vs unprotected output (line 127)
