Amazon Linux 2023 Security Advisory: ALAS2023-2026-3128
Advisory Released Date: 2026-09-29
Advisory Updated Date: 2026-09-29
Severity:
Important
Issue Overview:
When CURLOPT_PINNEDPUBLICKEY is configured alongside options that disable standard peer verification (CURLOPT_SSL_VERIFYPEER = 0 and CURLOPT_SSL_VERIFYHOST = 0), libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check under these disabled-verification conditions allows unauthenticated connections to succeed when they should be rejected. (CVE-2026-80230)
Affected Packages:
curl
Issue Correction:
Run dnf update curl --releasever 2023.12.20260928 or dnf update --advisory ALAS2023-2026-3128 --releasever 2023.12.20260928 to update your system.
More information on how to update your system can be found on this page: Amazon Linux 2023 documentation
