CVE-2023-30499Network attack vector

Editor-session script execution via reflected input

Published Aug 18, 2023 · Updated Apr 28, 2026

Reflected XSS in FolioVision FV Flowplayer Video Player 7.5.32.7212 and earlier allows remote attackers to execute script via crafted requests. Public CNA and vendor-linked disclosures do not identify the affected parameter, endpoint, or exact output-encoding failure. Exploitation requires an authenticated editor to follow a malicious link or submit a crafted request, and the script runs in that editor's browser context.
