Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsUpgrade curl
to version 8.7.0 or higher.
curl is a command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features.
Affected versions of this package are vulnerable to Improper Certificate Validation due to the improper validation of server certificates for TLS connections to hosts specified by IP addresses when using mbedTLS. This results in the application skipping the certificate verification process, exposing users to potential man-in-the-middle attacks by accepting unverified certificates.
Notes
This flaw is relevant for curl and libcurl built to use mbedTLS and affects all uses of TLS protocols.
This flaw also affects the curl command line tool.
