CVE-2026-71439

A flaw was found in Mermaid. Mermaid Radar Diagrams are susceptible to a denial of service vulnerability. A remote attacker could exploit this by providing excessively large values for the 'ticks' parameter. This can lead to high CPU usage, causing the rendering webpage or JavaScript process to...

CVE-2026-50159

A flaw was found in Mermaid, a JavaScript tool for creating diagrams and charts. An attacker who can provide diagram text can inject arbitrary CSS Cascading Style Sheets into the rendered web page. This is possible due to a vulnerability in how sibling combinator selectors are generated from...

CVE-2026-71438

A flaw was found in Mermaid, a JavaScript tool for creating diagrams. The tool's configuration application programming interfaces APIs, specifically mermaid.initialize, mermaidAPI.setConfig, and mermaidAPI.updateSiteConfig, are vulnerable to prototype pollution. This occurs because these APIs...

CVE-2026-71437

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...

Denial Of Service

Mermaid is vulnerable to Denial Of Service. The vulnerability is due to unrestricted ticks values in Radar Diagrams, allowing an attacker to trigger excessive CPU usage and potentially exhaust memory by causing prolonged rendering...

Prototype Pollution

Mermaid is vulnerable to Prototype Pollution. The vulnerability is due to assignWithDepth being used to deep-merge caller-supplied configuration into Mermaid's internal config, allowing prototype pollution when untrusted data is passed directly to configuration setters such as mermaid.initialize...

CSS Injection

Mermaid is vulnerable to CSS Injection. The vulnerability is due to sibling combinator selectors generated from attacker-controlled diagram class or ID names, allowing CSS injection that can alter the appearance or behavior of unrelated page elements...

Prototype Pollution

Mermaid is vulnerable to Prototype Pollution. The vulnerability is due to an Architecture Diagram group ID of proto being used directly as an object property key without validation, allowing an attacker who can supply diagram text to pollute Object.prototype...
