CVE-2026-35516

LinkAce is a self-hosted archive to collect website links. Prior to 2.5.4, LinkRepository::update and CheckLinksCommand::checkLink do not check for private IPs. An authenticated user can read responses from internal services (AWS IMDSv1, cloud metadata, internal APIs) by creating a link with a public URL and then updating it to a private IP. The links:check cron job makes the request server-side without IP filtering. This can expose cloud credentials, internal service data, and network topology. This vulnerability is fixed in 2.5.4.

Summary		(es) LinkAce es un archivo autoalojado para recopilar enlaces de sitios web. Antes de la versión 2.5.4, LinkRepository::update y CheckLinksCommand::checkLink no verifican IPs privadas. Un usuario autenticado puede leer respuestas de servicios internos (AWS IMDSv1, metadatos de la nube, APIs internas) creando un enlace con una URL pública y luego actualizándolo a una IP privada. El trabajo cron links:check realiza la solicitud del lado del servidor sin filtrado de IP. Esto puede exponer credenciales de la nube, datos de servicios internos y la topología de la red. Esta vulnerabilidad se corrige en la versión 2.5.4.
