Summary

Regular Expression Denial of Service in markdown

Details

All versions of markdown are vulnerable to Regular Expression Denial of Service (ReDoS). The markdown.toHTML() function has significantly degraded performance when parsing long strings containing underscores. This may lead to Denial of Service if the parser accepts user input.

Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
