Security

This release has been built with updated Go runtime 1.26.10 to address CVE-2026-111943 by rejecting certificate chains that include eight revoked eMudhra intermediate certificates.
Image pulls and pushes fail TLS certificate verification if a registry's certificate chain relies on one of the affected TLS intermediates.
Affected registries need a replacement certificate chain that does not use these intermediates.

The blocked intermediates are:

• Domain-validated TLS: EM DV TLS CA - G3B and EM DV TLS CA - G3C
• Organization-validated TLS: EM OV TLS CA - G3B and EM OV TLS CA - G3C
• Extended-validation TLS: EM EV TLS CA - G3B and EM EV TLS CA - G3C
• Code signing: EM OV CS CA - G3B and EM OV CS CA - G3C

The G3B intermediates belong to eMudhra BV, and the G3C intermediates belong to eMudhra Inc.
The keys for these intermediates were compromised.
