CVE-2026-48760
Last modified
CVE-2026-48760 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
