in the control panel\nA Remote Code Execution vulnerability exists in the Craft CMS 5 conditions system.\n\nThe `BaseElementSelectConditionRule::getElementIds()` method passes user-controlled string input\nthrough `renderObjectTemplate()` -- an unsandboxed Twig rendering function with escaping disabled.\n\nAny authenticated Control Panel user (including non-admin roles such as Author or Editor) can achieve full\nRCE by sending a crafted condition rule via standard element listing endpoints.\n\nThis vulnerability requires no admin privileges, no special permissions beyond basic control panel access, and\nbypasses all production hardening settings (allowAdminChanges: false, devMode: false,\nenableTwigSandbox: true).\n\nUsers should update to the patched 5.99 release to mitigate the issue.", "aliases": [ { "alias": "CVE-2026-31857" }, { "alias": "GHSA-fp5j-j7j4-mcxc" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/74586?format=api", "purl":
