From 3.9.0 until 3.26.0, template_from_string() compiles an inner template under a synthesized __string_template__<hash> name that can fall outside a SourcePolicyInterface sandbox decision, allowing a sandboxed template that can call template_from_string and include to render an inner template without security policy enforcement. This issue is fixed in version 3.26.0.","published":"2026-07-14T21:19:17.804Z","modified":"2026-08-12T03:51:46.112064875Z","cvss":null,"epss":{"score":0.00419,"percentile":0.34976,"asOf":"2026-08-18"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"twig/twig","fixedVersion":"3.26.0"}],"fix":{"url":"https://github.com/twigphp/Twig/commit/1cde8f2b62463f85d47995fc25f8241cb409d915","label":"twigphp/Twig@1cde8f2"},"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-2026-46634.json"},{"type":"ADVISORY","url":"https://github.com/twigphp/Twig/security/advisories/GHSA-24x9-r6q4-q93w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46634"},{"type":"FIX","url":"https://github.com/twigphp/Twig/commit/1cde8f2b62463f85d47995fc25f8241cb409d915"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.112064875Z"}}
