What is CVE-2026-11820?
CVE-2026-11820 is a medium-severity vulnerability in Redhat Enterprise Linux, published on 23 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.
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.
