CVE-2026-11820
CWE-532Published: June 23, 2026· Updated: Jun 26, 2026
Official Description
A flaw was found in the community.general Ansible collection's nexmo module.
The module constructs HTTP requests to the Vonage/Nexmo SMS API by encoding
API credentials (api_key and api_secret) into URL query parameters and
sending them via GET requests. This causes credentials to be exposed in web
server access logs, proxy logs, HTTP Referer headers, and network monitoring
tools, despite the Ansible argument specification marking these parameters
as no_log. An attacker with access to any of these logging or monitoring
points can obtain the full API credentials and gain unauthorized access to
the victim's Vonage/Nexmo account.
Technical Analysis
CVE-2026-11820 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 6.5.
