Twig is an open source template language for PHP. When in a sandbox mode,
the arrow parameter of the sort filter must be a closure to avoid
attackers being able to run arbitrary PHP functions. In affected versions
this constraint was not properly enforced and could lead to code injection
of arbitrary PHP code. Patched versions now disallow calling non Closure in
the sort filter as is the case for some other filters. Users are advised
to upgrade.
Notes
| Author | Note |
|---|---|
| ccdm94 | advisory mentions that all versions greater than 2.0.0 and less than 2.14.11 are affected, however, there is no ‘arrow’ parameter implemented in bionic’s version of Twig. As per commit 330024b6, support for the ‘arrow’ function was only added in Twig 2.12. |
