Mermaid radar diagrams are vulnerable to DoS
Quick fix
GHSA-rhh3-jpg6-66xh — mermaid: upgrade to the fixed version with the command below.
npm install mermaid@11.16.1Details
### Impact
Mermaid radar diagrams allow arbitrary large values for `ticks`, which can cause high CPU usage, freezing the webpage/JavaScript process for long periods of time, until the process is eventually killed due to OOM/running out of memory.
#### Proof-of-concept
```txt radar-beta axis a, b curve c {1, 1} ticks 1000000000 ```
