Описание
Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. From version 11.5.0 until 11.16.1, Mermaid Architecture Diagrams are vulnerable to prototype pollution when a diagram defines a group with an id of proto. Because the group id is used directly as an object property key without validation, an attacker who can supply diagram text can pollute Object.prototype, potentially affecting the behavior of the embedding application. This issue is fixed in version 11.16.1.
A flaw was found in Mermaid, a JavaScript tool for creating diagrams. This vulnerability, known as prototype pollution, occurs when a specially crafted diagram defines a group with a specific identifier. An attacker who can provide malicious diagram text can exploit this by manipulating core JavaScript object properties, potentially leading to arbitrary code execution or denial of service in the embedding application. This could allow an attacker to gain control over the application or disrupt its operations.
Отчет
This Moderate severity flaw in Mermaid Architecture Diagrams allows prototype pollution when processing specially crafted diagram text. An attacker could exploit this to corrupt application configuration, bypass security checks, or cause denial of service in Red Hat products that embed Mermaid, such as Red Hat OpenShift AI, Red Hat Build of Podman Desktop, and Red Hat OpenShift Dev Spaces. Direct remote code execution is not possible through this vulnerability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
