Highlights
Auth Bypass: 3 prior fixes. Scrutinize any change in this area.
acme/api/internal/secure/signer.go: most-fixed (1 issue). Treat as high-risk during review.
1 high-severity fix in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A missing return statement when parsing RSA private keys (loadPrivateKey) returned a nil key and nil error, creating severe authentication and trust-boundary bypasses.
Auth Bypass: Misidentifying signature algorithms for opaque private keys by neglecting proper public key type assertions can lead to cryptographic signature failures or bypasses.
Cleartext Transmission of Sensitive Information: The client transport failed to strictly enforce secure connections, requiring a wrapper round tripper assertion to reject insecure non-HTTPS communications to ACME servers.
