Regular Expression Denial of Service in papaparse

Versions of papaparse prior to 5.2.0 are vulnerable to Regular Expression Denial of Service (ReDos). The parse function contains a malformed regular expression that takes exponentially longer to process non-numerical inputs. This allows attackers to stall systems and lead to Denial of Service.

Recommendation

Upgrade to version 5.2.0 or later.
