CVE-2026-31889

Estado: AnalizadaAlta (8.9)—

Shopware is an open commerce platform. Prior to 6.6.10.15 and 6.7.8.1, a vulnerability in the Shopware app registration flow that could, under specific conditions, allow attackers to take over the communication channel between a shop and an app. The legacy app registration flow used HMAC‑based authentication without sufficiently binding a shop installation to its original domain. During re‑registration, the shop-url could be updated without proving control over the previously registered shop or domain.

Leer descripción completaMostrar menos

This made targeted hijacking of app communication feasible if an attacker possessed the relevant app‑side secret. By abusing app re‑registration, an attacker could redirect app traffic to an attacker‑controlled domain and potentially obtain API credentials intended for the legitimate shop. This vulnerability is fixed in 6.6.10.15 and 6.7.8.1.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS AV:N sin PR/UI justifica T1190. El atacante hijackea el canal app-shop para obtener credenciales API (T1078) e interceptar tráfico (T1557) redirigiendo a dominio controlado (proxy/SSRF T1090.001).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Antes de las versiones 6.6.10.15 y 6.7.8.1, una vulnerabilidad en el flujo de registro de aplicaciones de Shopware que podría, bajo condiciones específicas, permitir a los atacantes tomar el control del canal de comunicación entre una tienda y una aplicación. El flujo de registro de aplicaciones heredado utilizaba autenticación basada en HMAC sin vincular suficientemente una instalación de tienda a su dominio original. Durante el nuevo registro, la URL de la tienda podría actualizarse sin probar el control sobre la tienda o dominio previamente registrado. Esto hizo factible el secuestro dirigido de la comunicación de la aplicación si un atacante poseía el secreto relevante del lado de la aplicación. Al abusar del nuevo registro de la aplicación, un atacante podría redirigir el tráfico de la aplicación a un dominio controlado por el atacante y potencialmente obtener credenciales de API destinadas a la tienda legítima. Esta vulnerabilidad está corregida en las versiones 6.6.10.15 y 6.7.8.1."
