GMS-2020-421: Regular Expression Denial of Service in papaparse

September 4, 2020 (updated October 4, 2021)

Versions of papaparse 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. Upgrade to or later.
