From 3.24.0 until 3.26.0, object-destructuring assignment compiles CoreExtension::getAttribute() with the sandbox argument hardcoded to false, disabling property and method policy checks and allowing an attacker with write access to a sandboxed Twig template to read public properties or invoke public getters on objects passed to the template engine. This issue is fixed in version 3.26.0.","published":"2026-07-14T21:13:42.321Z","modified":"2026-08-12T03:51:36.521422003Z","cvss":null,"epss":{"score":0.00351,"percentile":0.28228,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"twig/twig","fixedVersion":"3.26.0"}],"fix":null,"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-2026-46639.json"},{"type":"ADVISORY","url":"https://github.com/twigphp/Twig/security/advisories/GHSA-mm6w-gr99-p3jj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46639"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:36.521422003Z"}}
