CVE-2025-66081Network attack vector

Stored script execution via undisclosed rendering path

Published Nov 21, 2025 · Updated Nov 21, 2025

Stored cross-site scripting in Jeff Starr Head Meta Data 20250327 and earlier allows remote authenticated users to inject scripts. Published advisories do not identify the affected field, function, or rendering path; they state only that input is insufficiently sanitized and output is insufficiently escaped. Author-level access is required to store the payload, and execution occurs when another user visits the affected page, permitting script actions in that visitor's browser context.
