{"id":"UBUNTU-CVE-2022-39261","details":"Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue 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. Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such template names. There are no known workarounds aside from upgrading.","modified":"2026-02-04T23:49:13.512486Z","published":"2022-09-28T14:15:00Z","related":["USN-5947-1"],"upstream":["CVE-2022-39261"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-39261"},{"type":"REPORT","url":"https://github.com/twigphp/Twig/security/advisories/GHSA-52m2-vc4m-jj33"},{"type":"REPORT","url":"https://github.com/twigphp/Twig/commit/35f3035c5deb0041da7b84daf02dea074ddc7a0b"},{"type":"REPORT","url":"https://github.com/twigphp/Twig/commit/35f3035c5deb0041da7b84daf02dea074ddc7a0b"},{"type":"REPORT","url":"https://www.drupal.org/sa-core-2022-016"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5947-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-39261"}],"affected":[{"package":{"name":"twig","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/twig@1.23.1-1ubuntu4+esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.23.1-1ubuntu4+esm1"}]}],"versions":["1.20.0-1","1.23.1-1ubuntu1","1.23.1-1ubuntu4"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"1.23.1-1ubuntu4+esm1","binary_name":"php-twig"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-39261.json"}},{"package":{"name":"twig","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/twig@2.4.6-1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.6-1ubuntu0.1~esm1"}]}],"versions":["1.24.0-2ubuntu1","2.4.4-2ubuntu1","2.4.6-1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"2.4.6-1ubuntu0.1~esm1","binary_name":"php-twig"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-39261.json"}},{"package":{"name":"php-twig","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/php-twig@2.12.5-1ubuntu0.1~esm1?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.5-1ubuntu0.1~esm1"}]}],"versions":["2.11.3-2","2.12.1-1","2.12.2-1","2.12.3-1","2.12.5-1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-cssinliner-extra"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-extra-bundle"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-html-extra"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-inky-extra"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-intl-extra"},{"binary_version":"2.12.5-1ubuntu0.1~esm1","binary_name":"php-twig-markdown-extra"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-39261.json"}},{"package":{"name":"php-twig","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/php-twig@3.3.8-2ubuntu4+esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.8-2ubuntu4+esm1"}]}],"versions":["3.3.2-1ubuntu3","3.3.4-1","3.3.6-1","3.3.7-1","3.3.8-2ubuntu4"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-cache-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-cssinliner-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-extra-bundle"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-html-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-inky-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-intl-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-markdown-extra"},{"binary_version":"3.3.8-2ubuntu4+esm1","binary_name":"php-twig-string-extra"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-39261.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
