CVE-2026-48808
Published:July 14, 2026
Updated:July 19, 2026
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. This issue is fixed in version 3.27.0.
Affected Packages
twig/twig (PHP):
Affected version(s) >=dev-block-fix <v3.27.0
Fix Suggestion:
Update to version v3.27.0
