UBUNTU-CVE-2026-48805
A vulnerability in the PHP Twig template language prior to version 3.27.0 allows legacy internal wrapper functions to bypass sandbox callable restrictions due to not forwarding the current sandbox state. This issue is fixed in Twig version 3.27.0. Multiple specific Ubuntu package versions of php-twig are affected.
AI Analysis
Technical Summary
Twig versions prior to 3.27.0 contain deprecated internal wrappers in src/Resources/core.php that do not forward the current sandbox state to certain functions (CoreExtension::checkArrow(), arraySome(), and arrayEvery()). This allows legacy calls such as twig_array_some(), twig_array_every(), and twig_check_arrow_in_sandbox() to bypass sandbox callable restrictions, potentially weakening sandbox security. The vulnerability is resolved in version 3.27.0 of Twig.
Potential Impact
The vulnerability allows bypassing of sandbox callable restrictions in Twig templates, which could lead to unauthorized execution of code within the sandbox environment. This weakens the intended security controls of the sandbox, potentially allowing attackers with limited privileges to execute restricted functions.
Mitigation Recommendations
Upgrade php-twig to version 3.27.0 or later where this issue is fixed. The affected Ubuntu package versions listed should be updated to versions that include this fix. Patch status is confirmed by the fix in Twig 3.27.0.
