What happened and what to do
On September 28, 2026, Ubuntu security advisory USN-8487-2 corrected an incomplete fix for CVE-2026-8927 and covered vulnerabilities in curl. The reported risks include unintended TLS settings in STARTTLS connections, unauthorized access to authenticated resources, exposure of credentials and cookies, denial of service, and possible code execution. The issues affect different Ubuntu releases; some apply only to specific releases.\n\nA company can inventory systems and applications that use curl, identify affected versions and releases, and plan to apply updates. It can also test integrations that rely on authentication, proxies, and TLS, and monitor systems for issues after remediation.
