{"id":"CVE-2026-45064","aliases":["GHSA-h5vq-qfcg-4m6p"],"url":"https://o3.security/vulnerability/CVE-2026-45064","summary":"Symfony: HtmlSanitizer URL Attributes Pass Through BiDi Override Characters → Visual href Spoofing","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0-BETA1 until 6.4.40, 7.4.12, and 8.0.12, UrlSanitizer::parse() passes Unicode explicit-direction BiDi formatting characters through into sanitized href and src attributes, allowing sanitized content to display a link destination that visually differs from the actual destination and enabling phishing-style visual spoofing. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.","published":"2026-07-14T18:35:53.530Z","modified":"2026-08-12T03:51:44.162145942Z","cvss":null,"epss":{"score":0.00293,"percentile":0.21906,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"6.4.40"},{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"8.0.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"6.4.40"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"8.0.12"}],"fix":{"url":"https://github.com/symfony/symfony/commit/743a435e948b897ef2b5564ac438d4beb95d2526","label":"symfony/symfony@743a435"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v6.4.40"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v7.4.12"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v8.0.12"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45064.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-h5vq-qfcg-4m6p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45064"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/743a435e948b897ef2b5564ac438d4beb95d2526"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.162145942Z"}}
