Vulnerability intelligence
CVE-2026-92387. It is not in the current CISA KEV record we collected. That does not prove exploitation has not occurred.
USN-8927-1 fixed vulnerabilities in curl.
By permanently omitting the final control-response line, a malicious FTP, IMAP, POP3, or SMTP server can exploit libcurl and completely bypass its configured transfer timeout mechanism, indefinitely blocking all concurrent transfers bound to the same multi-handle.
