{"id":"DEBIAN-CVE-2026-47732","details":"Twig is a template language for PHP. Prior to 3.26.0, several Twig language constructs trigger PHP string coercion on a Stringable operand without consulting SecurityPolicy::checkMethodAllowed(), allowing a sandboxed template author to invoke __toString() on objects reachable in the render context through conditional expressions, comparison operators, tests, template-loading tags, dynamic attribute names, spread arguments, the do tag, and the .. range operator. This issue is fixed in version 3.26.0.","modified":"2026-09-01T16:06:47.578341510Z","published":"2026-07-14T22:16:59.667Z","upstream":["CVE-2026-47732"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-47732"}],"affected":[{"package":{"name":"php-twig","ecosystem":"Debian:12","purl":"pkg:deb/debian/php-twig?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.10.1-1","3.10.3-1","3.11.0-1","3.13.0-1","3.14.0-1","3.14.0-2","3.14.0-3","3.14.0-4","3.14.2-1","3.14.2-2","3.14.2-3","3.15.0-1","3.15.0-2","3.17.1-1","3.17.1-2","3.18.0-1","3.18.0-2","3.18.0-4","3.18.0-5","3.18.0-6","3.18.0-7","3.19.0-1","3.19.0-1~bootstrap","3.20.0-1","3.20.0-1~bootstrap","3.20.0-2","3.21.1-1","3.21.1-2","3.21.1-3","3.22.0-1","3.22.0-2","3.22.1-1","3.22.1-2","3.22.1-3","3.22.2-1","3.22.2-2","3.23.0-1","3.23.0-2","3.24.0-1","3.26.0-1","3.27.0-1","3.27.1-1","3.28.0-1","3.5.1-1","3.5.1-1+deb12u1","3.5.1-1+deb12u2","3.5.1-1+deb12u3","3.6.0-1","3.6.1-1","3.7.0-1","3.7.1-1","3.7.1-2","3.7.1-3","3.8.0-1","3.8.0-2","3.8.0-3","3.8.0-4","3.9.3-1","4.0.0~alpha1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47732.json"}},{"package":{"name":"php-twig","ecosystem":"Debian:13","purl":"pkg:deb/debian/php-twig?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.27.0-0+deb13u1"}]}],"versions":["3.20.0-2","3.21.1-1","3.21.1-2","3.21.1-3","3.22.0-1","3.22.0-2","3.22.1-1","3.22.1-2","3.22.1-3","3.22.2-1","3.22.2-2","3.23.0-1","3.23.0-2","3.24.0-1","3.26.0-0+deb13u1","3.26.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47732.json"}},{"package":{"name":"php-twig","ecosystem":"Debian:14","purl":"pkg:deb/debian/php-twig?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.26.0-1"}]}],"versions":["3.20.0-2","3.21.1-1","3.21.1-2","3.21.1-3","3.22.0-1","3.22.0-2","3.22.1-1","3.22.1-2","3.22.1-3","3.22.2-1","3.22.2-2","3.23.0-1","3.23.0-2","3.24.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47732.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
