CVE-2023-30752Network attack vector

Stored browser-script execution via undisclosed input handling

Published Aug 14, 2023 · Updated Apr 28, 2026

Stored XSS in External Videos 2.0.1 and earlier allows remote authenticated users with administrator access to run script in a viewer's browser. Published advisories do not identify the affected field, function, or missing sanitization or output-encoding operation. Exploitation requires administrator-level access and a later user to view the stored content; the script then executes in that user's browser context.
