Administrator-level stored XSS via unsanitized settings
Published Sep 27, 2023 · Updated Apr 28, 2026
Stored XSS in PluginOps Landing Page Builder 1.5.1.2 and earlier allows remote authenticated users to store script via admin settings. Public advisories identify insufficient input sanitization and output escaping in those settings but do not name the affected field or function. Administrator access is required to plant the payload, and another user's interaction is required to execute it in that user's browser context.
