CVE-2026-12257

Versions of Mura CMS prior to 10.0.712 contain a critical remote code execution (RCE) vulnerability. The flaw is located in the endpoint “/index.cfm/_api/json/v1/default”, where the “method” parameter in POST requests is not properly validated or sanitised before being processed by the ColdFusion engine. As a result, a remote attacker could exploit this vulnerability to inject and execute arbitrary CFML (ColdFusion Markup Language) expressions and instantiate malicious Java objects, thereby compromising the system’s security.
