      "value": "LinkAce is a self-hosted archive to collect website links. In versions 2.3.1 and below, the social media sharing functionality contains a Stored Cross-Site Scripting (XSS) vulnerability that allows any authenticated user to inject arbitrary JavaScript by creating a link with malicious HTML in the title field. When a user views the link details page and the shareable links are rendered, the malicious JavaScript executes in their browser. This vulnerability affects multiple sharing services and can be exploited to steal session cookies, perform actions on behalf of users, or deliver malware. This issue is fixed in version 2.4.0."

En las versiones 2.3.1 e inferiores, la funcionalidad para compartir en redes sociales contiene una vulnerabilidad de Stored Cross-Site Scripting (XSS) que permite a cualquier usuario autenticado inyectar JavaScript arbitrario creando un enlace con HTML malicioso en el campo del título. Cuando un usuario ve la página de detalles del enlace y se renderizan los enlaces compartibles, el JavaScript malicioso se ejecuta en su navegador. Esta vulnerabilidad afecta a múltiples servicios para compartir y puede ser explotada para robar cookies de sesión, realizar acciones en nombre de los usuarios o entregar malware. Este problema está solucionado en la versión 2.4.0."
