CVE-2026-48808: Twig: Sandbox property allowlist bypass via the `column` filter under `SourcePolicyInterface`

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-14 · updated 2026-10-24
• Weakness: CWE-693

Description

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 products

• twigphp Twig: before 3.27.0 — fixed in 3.27.0

How to fix

Upgrade to a fixed version: twigphp Twig 3.27.0. Check the vendor advisory for mitigations.
