CVE-2025-14524 (opens in a new tab)How to fix?
Upgrade curl to version 8.18.0 or higher.
Overview
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 Insufficiently Protected Credentials during the cross-protocol redirect when OAuth2 bearer is used and username component is set in redirect-to URL. An attacker can obtain sensitive authentication credentials by triggering a cross-protocol redirect from an HTTP(S) transfer to a different protocol such as IMAP, LDAP, POP3, or SMTP, causing the bearer token to be sent to an unintended host.
Note:
This vulnerability is a bypass of the CVE-2022-27774 fix.
