Administrator-level script execution via unsanitized inputs
Published Oct 15, 2021 · Updated Feb 14, 2025
Stored XSS in Business Manager 1.4.5 and earlier allows remote authenticated users to inject scripts through plugin inputs. The public advisory identifies insufficient validation and sanitization throughout the plugin but does not disclose affected fields, handlers, or rendering sinks. Administrator access is required, and exposure is limited to multisite installations or sites where administrators lack unfiltered_html.
