What is CVE-2026-112773?

Craft CMS versions prior to 5.11.0 are vulnerable to a remote code execution issue that enables authenticated Control Panel users to bypass the Twig sandbox's security measures. By supplying unvalidated input to methods like getNext, getPrev, or getOwners, attackers can manipulate the system to inject harmful event handlers into the Yii configuration. This unauthorized code execution poses a significant risk, allowing malicious actions to be performed as the web user during element queries.

Affected Version(s)

cms 5.0.0 < 5.11.0
