This vulnerability could be exploited by an attacker to redirect legitimate users to malicious websites, potentially leading to phishing attacks or the delivery of exploit kits.\n\nOpen Redirection via returnUrl\u00a0Parameter: An Open Redirection vulnerability exists in the /s/action/unlock/user.user/0\u00a0endpoint. The returnUrl\u00a0parameter, intended for post-action redirection, is not properly validated. This allows an attacker to craft a URL that, when clicked by a user, redirects them to an arbitrary external website controlled by the attacker.\n\nMitigationUpdate Mautic to a version that properly validates or sanitizes the returnUrl\u00a0parameter to ensure that redirects only occur to trusted, internal URLs or explicitly whitelisted domains."}, {"lang": "es", "value": "Resumen: Este aviso aborda una vulnerabilidad de redirecci\u00f3n abierta en el endpoint de desbloqueo de usuarios de Mautic. Un atacante podr\u00eda aprovechar esta vulnerabilidad para redirigir a usuarios leg\u00edtimos a sitios web maliciosos, lo que podr\u00eda provocar ataques de phishing o la entrega de kits de explotaci\u00f3n. Redirecci\u00f3n abierta mediante el par\u00e1metro returnUrl: Existe una vulnerabilidad de redirecci\u00f3n abierta en el endpoint /s/action/unlock/user.user/0. El par\u00e1metro returnUrl, destinado a la redirecci\u00f3n posterior a la acci\u00f3n, no est\u00e1 validado correctamente. Esto permite a un atacante manipular una URL que, al hacer clic en ella, redirige a un sitio web externo arbitrario controlado por el atacante. Mitigaci\u00f3n: Actualice Mautic a una versi\u00f3n que valide o depure correctamente el par\u00e1metro returnUrl para garantizar que las redirecciones solo se realicen a URL internas de confianza o a dominios expl\u00edcitamente incluidos en la lista blanca."}], "lastModified": "2026-04-15T00:35:42.020", "sourceIdentifier": "security@mautic.org"}
