CVE-2021-27293

Name of the Vulnerable Software and Affected Versions RestSharp versions prior to 106.11.8-alpha.0.13

Description The issue arises from a vulnerable regular expression used when converting strings into DateTimes, making it susceptible to Regular Expression Denial of Service (ReDoS). If a server responds with a malicious string, the client using the affected software will be stuck processing it for an exceedingly long time, allowing the remote server to trigger a Denial of Service.

Recommendations For versions prior to 106.11.8-alpha.0.13, update to version 106.11.8-alpha.0.13 or later to resolve the issue. As a temporary workaround, consider restricting the use of the DateTime conversion function to minimize the risk of exploitation.
