CVE-2022-39261
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Twig versions 1.x prior to 1.44.7
Twig versions 2.x prior to 2.15.3
Twig versions 3.x prior to 3.4.3
Description
The issue arises when the filesystem loader loads templates for which the name is a user input. It is possible to use the
source or include statement to read arbitrary files from outside the templates' directory when using a namespace like @somewhere/../some.file. In such a case, validation is bypassed.Recommendations
For versions 1.x prior to 1.44.7, update to version 1.44.7 or later.
For versions 2.x prior to 2.15.3, update to version 2.15.3 or later.
For versions 3.x prior to 3.4.3, update to version 3.4.3 or later.
As a temporary workaround, consider restricting the use of the
source and include statements with user-input template names until a patch is available.Exploit
