{"id":"CVE-2026-46637","summary":"Twig: HTML-output filters in twig/* extras incorrectly declared `is_safe =\u003e ['all']`","details":"Twig is a template language for PHP. Prior to 3.26.0, several filters in twig/markdown-extra and twig/cssinliner-extra are registered with is_safe =\u003e [all], causing Twig to treat plain text or HTML output as safe in HTML, JavaScript, CSS, URL, and other contexts where the output is not properly escaped. This issue is fixed in version 3.26.0.","aliases":["GHSA-jv8m-2544-3pg3"],"modified":"2026-07-18T03:42:00.405813620Z","published":"2026-07-14T21:25:20.141Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46637.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-116"]},"references":[{"type":"WEB","url":"https://github.com/twigphp/Twig/releases/tag/v3.26.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46637.json"},{"type":"ADVISORY","url":"https://github.com/twigphp/Twig/security/advisories/GHSA-jv8m-2544-3pg3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46637"},{"type":"FIX","url":"https://github.com/twigphp/Twig/commit/84982072c79a7417b0d158a401d91344f3658299"},{"type":"FIX","url":"https://github.com/twigphp/Twig/commit/e36489d3521ecbfc08bdcc61294302557035f14a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/twigphp/twig","events":[{"introduced":"0"},{"fixed":"1fcae487b180d78e6351f4e0afa91f9eab96a2bc"},{"fixed":"84982072c79a7417b0d158a401d91344f3658299"},{"fixed":"e36489d3521ecbfc08bdcc61294302557035f14a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.26.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:symfony:twig:*:*:*:*:*:*:*:*"}}],"versions":["v3.25.0","v3.24.0","v3.23.0","v3.22.2","v3.22.1","v3.22.0","v3.21.1","v3.21.0","v3.20.0","v3.19.0","v3.18.0","v3.17.1","v3.17.0","v3.16.0","v3.15.0","v3.14.0","v3.11.0","v3.13.0","v3.12.0","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.0","v3.7.1","v3.7.0","v3.6.1","v3.6.0","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.10","v3.3.9","v3.3.8","v3.3.7","v3.3.6","v3.3.5","v3.3.4","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.1","v3.1.1","v3.1.0","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v3.0.0-BETA1","v2.8.1","v2.8.0","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.8","v2.4.7","v2.4.6","v2.4.5","v2.4.4","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v1.18.0","v1.17.0","v1.16.3","v1.16.2","v1.16.1","v1.16.0","v1.15.1","v1.15.0","v1.14.2","v1.14.1","v1.14.0","v1.13.2","v1.13.1","v1.13.0","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.12.0-RC1","v1.11.1","v1.11.0","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.5.1","v1.6.0","v1.5.0","v1.5.0-RC2","v1.5.0-RC1","v1.4.0","v1.4.0-RC2","v1.4.0-RC1","v1.3.0","v1.3.0-RC1","v1.2.0","v1.2.0-RC1","v1.1.2","v1.1.1","v1.1.0","v1.1.0-RC3","v1.1.0-RC2","v1.1.0-RC1","v1.0.0","v1.0.0-RC2","v1.0.0-RC1","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.2","v0.9.1","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46637.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]}
