{"id":"CVE-2026-48760","aliases":["GHSA-v3wm-qf9p-c549"],"url":"https://o3.security/vulnerability/CVE-2026-48760","summary":"Symfony: HtmlSanitizer URL Parser Deny Gates Underinclusive: Percent-Encoded BiDi Marks and Unicode Whitespace Bypass Visual-Spoofing Defense","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0 until 6.4.41, 7.4.13, and 8.0.13, UrlSanitizer::parse() rejected raw BiDi formatting characters but not percent-encoded forms and used an ASCII-only whitespace check, allowing sanitized URLs to retain visual-spoofing characters that downstream consumers could decode or display. This issue is fixed in versions 6.4.41, 7.4.13, and 8.0.13.","published":"2026-07-14T19:11:42.179Z","modified":"2026-08-12T03:51:35.585389944Z","cvss":null,"epss":{"score":0.00338,"percentile":0.27145,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"6.4.41"},{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"7.4.13"},{"ecosystem":"Packagist","name":"symfony/html-sanitizer","fixedVersion":"8.0.13"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"6.4.41"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"7.4.13"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"8.0.13"}],"fix":{"url":"https://github.com/symfony/symfony/commit/b21a626fd90f5c12d2db432c629eed3e780ba2f8","label":"symfony/symfony@b21a626"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v6.4.41"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v7.4.13"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v8.0.13"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48760.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-v3wm-qf9p-c549"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48760"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/b21a626fd90f5c12d2db432c629eed3e780ba2f8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.585389944Z"}}
