CVE-2026-47901

Logseq is vulnerable to a sandbox escape flaw where plugins running in sandboxed iframes can inject arbitrary HTML attributes, such as event handlers, into their container element in the host DOM. Due to a disabled Content Security Policy (CSP), this allows a malicious plugin to execute arbitrary JavaScript in the privileged host context, potentially gaining unauthorized access to filesystem APIs. While only version v0.10.15 was tested and confirmed as vulnerable, status of other versions is unknown since this issue was not addressed by a patch.

Summary		(es) Logseq es vulnerable a una falla de escape de sandbox donde los plugins que se ejecutan en iframes en sandbox pueden inyectar atributos HTML arbitrarios, como controladores de eventos, en su elemento contenedor en el DOM del host. Debido a una Política de Seguridad de Contenido (CSP) deshabilitada, esto permite que un plugin malicioso ejecute JavaScript arbitrario en el contexto privilegiado del host, obteniendo potencialmente acceso no autorizado a las API del sistema de archivos. Si bien solo la versión v0.10.15 fue probada y confirmada como vulnerable, el estado de otras versiones es desconocido ya que este problema no fue abordado por un parche.
