Mishandled trust preferences for root certificates on Darwin in crypto/x509

Not rated yet Go

Severity: Not rated yet; No source has published a CVSS score yet
Exploit chance (EPSS): 1.44%; Chance of exploitation in the next 30 days. Higher than 73.23% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: —; Not classified
Fix: 1.7.4; Upgrade stdlib to this version or later

Description

On Darwin, user's trust preferences for root certificates were not honored. If the user had a root certificate loaded in their Keychain that was explicitly not trusted, a Go program would still verify a connection using that root certificate.

Affected versions

Go

Package	Vulnerable	Fixed in
stdlib	`< 1.6.4` `>= 1.7.0-0, < 1.7.4`	`1.6.4` `1.7.4`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

stdlib Go → `1.7.4`

go

go get stdlib@v1.7.4 && go mod tidy
