Mocha is vulnerable to ReDoS attack. If the stack trace in utils.js begins with a large error message, and full-trace is not enabled, utils.stackTraceFilter() will take exponential run time.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
