Twig versions 2.16.x and 3.9.0 through 3.25.x contain a sandbox bypass vulnerability when using a SourcePolicyInterface that allows attackers with template rendering capabilities to pass arbitrary PHP callables to sort, filter, map, and reduce filters. Attackers can exploit the runtime check that fails to use the current template source to bypass sandbox restrictions and execute arbitrary code when the sandbox is enabled through a source policy rather than globally.

The remote Ubuntu 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8408-1 advisory.

    It was discovered that Twig did not properly validate PHP callables when using a source policy. An     authenticated user could possibly use this issue to execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6311 advisory.

    Multiple security vulnerabilities were discovered in Twig, a template     engine for PHP, which could result in PHP code injection, sandbox bypass     or cross-site scripting.

    For the stable distribution (trixie), these problems have been fixed in     version 3.27.0-0+deb13u1.

    We recommend that you upgrade your php-twig packages.

    For the detailed security status of php-twig please refer to     its security tracker page at:
