Pull request overview
This PR attempts to upgrade the Go toolchain from versions 1.25.2/1.25.4 to 1.25.5 to address CVE-2025-61729, a high-severity DoS vulnerability in the crypto/x509 package. However, there is a critical issue: Go 1.25.5 does not appear to be a valid or existing version. The correct target version should be verified, likely Go 1.24.11 or a 1.23.x patch release.
Key Changes:
