CVE-2019-19134 — Heroplugins Hero Maps Premium security vulnerability
The Hero Maps Premium plugin 2.2.1 and prior for WordPress is prone to unauthenticated XSS via the views/dashboard/index.php p parameter because it fails to sufficiently sanitize user-supplied input. An attacker may leverage this issue to inject HTML or arbitrary JavaScript within the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based tokens or to launch other attacks.

Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
