Craft CMS versions >= 5.0.0-RC1 before 5.10.6 and >= 4.0.0-RC1 before 4.18.2 interpolate environment variables and secrets (via ${ENV_VAR} strings in the elementId parameter) into Twig templates before rendering, even when the Twig sandbox is enabled. An authenticated attacker with control panel access can render a malicious sandboxed Twig template and, using a blind error-based technique across many requests, incrementally leak arbitrary environment variables and secrets. These can be abused to forge sessions (via CRAFT_SECURITY_KEY), escalate privileges, and steal database, SMTP, API, or blob storage credentials. Fixed in 5.10.6 and 4.18.2.

Craft CMS versions 4.0.0-RC1 through before 4.18.2 and 5.0.0-RC1 through before 5.10.6 contain a vulnerability where authenticated users with control panel access can leak secret environment variables. This occurs because environment variables are interpolated into Twig templates even when the Twig sandbox is enabled, allowing secrets to be extracted via blind error-based techniques. The vulnerability enables attackers to incrementally exfiltrate sensitive secrets such as the CRAFT_SECURITY_KEY, database credentials, and API keys, potentially leading to session forgery and privilege escalation.
