CVE-2026-48760 Details
Description
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.
A vulnerability exists in the Symfony framework's UrlSanitizer component, specifically in versions 6.1.0 prior to 6.4.41, 7.4.13, and 8.0.13. The issue arises because the UrlSanitizer::parse() method fails to properly reject percent-encoded Bidirectional (BiDi) formatting characters and uses an inadequate whitespace check. This oversight allows sanitized URLs to retain visual-spoofing characters, which can be decoded and displayed by downstream consumers, potentially leading to phishing or other security risks.
Users can upgrade to Symfony versions 6.4.41, 7.4.13, or 8.0.13, where this vulnerability has been fixed.
