{"cve":"CVE-2022-39261","nvd":{"published":"2022-09-28T14:15:10.827","modified":"2026-06-17T04:58:01.430","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://github.com/twigphp/Twig/commit/35f3035c5deb0041da7b84daf02dea074ddc7a0b","https://github.com/twigphp/Twig/security/advisories/GHSA-52m2-vc4m-jj33","https://lists.debian.org/debian-lts-announce/2022/10/msg00016.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2OKRUHPVLIQVFPPJ2UWC3WV3WQO763NR/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AUVTXMNPSZAHS3DWZEM56V5W4NPVR6L7/"],"products":["debian:debian_linux","drupal:drupal","fedoraproject:fedora","symfony:twig"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-39261","score":0.03174,"percentile":0.88044,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
