CVE-2025-53206Network attack vector

Contributor-level stored XSS

Published Jun 27, 2025 · Updated Apr 28, 2026

Stored XSS in HasThemes HT Mega – Absolute Addons for WPBakery Page Builder 1.0.8 and earlier allows remote authenticated users to run scripts. The public advisory identifies insufficient input sanitization and output escaping in page content but does not disclose the affected element, parameter, or function. Contributor-level access is required to store a payload, and execution occurs only when another user opens the injected page, exposing that user's browser session to attacker-controlled script actions.
