CVE-2026-57319Network attack vector

Script execution via undisclosed reflected XSS

Published Jun 26, 2026 · Updated Jun 26, 2026

Reflected XSS in FOX 1.4.8 and earlier allows remote attackers to run script in a privileged user's browser via a crafted request. Neither the CNA record nor its linked advisory identifies the affected request parameter, code path, or output sink. Exploitation is unauthenticated but requires a privileged user to open attacker-controlled content, enabling script execution in that user's browser context.
