CVE-2026-11819

Estado: AnalizadaMedia (5.5)—

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:

Impact:

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

Leer descripción completaMostrar menos

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 1: PoC execution showing passphrase in plaintext output

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