Name of the Vulnerable Software and Affected Versions beautiful-mermaid versions prior to 0.1.3

Description The software contains an SVG attribute injection issue that can lead to cross-site scripting (XSS) when rendering attacker-controlled Mermaid diagrams. User-controlled values from Mermaid style and classDef directives are interpolated into SVG attribute values without proper escaping. This allows crafted input to break out of an attribute context and inject arbitrary SVG elements/attributes into the rendered output. When the generated SVG is embedded in a web page, this can result in script execution in the context of the embedding origin.

Recommendations Update beautiful-mermaid to version 0.1.3 or later.
