Last modified

CVE-2026-48808 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Twig is a template language for PHP. Prior to 3.27.0, the column filter passes the active sandbox state as a boolean but does not forward the current Source to SandboxExtension::checkPropertyAllowed(), so SourcePolicyInterface decisions are lost and a template author can read public or magic properties not allowed by the sandbox policy. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
