Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. From version 10.6.0 until 10.9.8 and 11.16.1, Mermaid XY Charts are vulnerable to an infinite loop denial of service in the setXAxisRangeData function when configuring an X-Axis with invalid parameters. Because each loop iteration appends an element to an array, this generally causes a RangeError to appear after a few seconds, but it may instead cause the page or JavaScript process to crash from memory exhaustion, depending on the environment. This issue is fixed in versions 10.9.8 and 11.16.1.

A flaw was found in Mermaid XY Charts. A remote attacker could exploit this by providing invalid parameters when configuring an X-Axis. This could lead to an infinite loop, causing a denial of service (DoS) due to memory exhaustion and potentially crashing the page or JavaScript process.
