CVE-2024-37488Network attack vector

Stored script execution via iframe insertion

Published Jul 21, 2024 · Updated Apr 28, 2026

Stored XSS in the HelloAsso WordPress plugin 1.1.9 and earlier allows remote authenticated users to inject scripts into site pages. The iframe-insertion path stores contributor-supplied content without sufficient input sanitization or output escaping, so the content is emitted as executable browser script. Contributor-level access is required, and the payload executes when another user opens the injected page, enabling actions in that viewer's browser context.
