Summary
Regular Expression Denial of Service in papaparse
Details

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.

Severity
7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
