A cross-site scripting (XSS) vulnerability has been identified in HotGo versions 1.0 through 2.0. This weakness resides within the /web/src/layout/components/Header/MessageList.vue endpoint, allowing attackers to inject malicious scripts. Successful exploitation could lead to session hijacking or data theft, impacting users of affected HotGo instances. A public proof-of-concept exists, increasing the risk of immediate exploitation.
The XSS vulnerability in HotGo allows an attacker to inject arbitrary JavaScript code into the application. This code executes within the context of the user's browser, granting the attacker the ability to steal cookies, redirect users to malicious websites, or deface the application. Given the public availability of a proof-of-concept, the risk of exploitation is significant. Attackers could leverage this to compromise user accounts, gain unauthorized access to sensitive data, or launch further attacks against the underlying infrastructure. The impact is amplified if HotGo is used in environments handling sensitive information or integrated with other critical systems.
This vulnerability is publicly disclosed and a proof-of-concept is available, indicating a high probability of exploitation. The CVE has been published, and the vendor has not responded to early disclosure attempts. The CVSS score is LOW, but the public PoC significantly increases the risk. It is currently not listed on CISA KEV.

The primary mitigation for CVE-2026-5253 is to upgrade to a patched version of HotGo. As no fixed version is currently specified, monitor the vendor's website for updates. Until a patch is available, consider implementing input validation and output encoding on the affected endpoint (/web/src/layout/components/Header/MessageList.vue) to sanitize user-supplied data. Web application firewalls (WAFs) configured to detect and block XSS payloads can also provide a temporary layer of protection. Regularly review access logs for suspicious activity, such as unusual JavaScript execution patterns.
Actualizar HotGo a una versión parcheada que solucione la vulnerabilidad XSS. Dado que el proveedor no ha respondido, se recomienda buscar parches no oficiales o considerar alternativas si la vulnerabilidad representa un riesgo significativo.
