GHSA-PWJX-QHCG-RVJ4 webpki: CRLs not considered authoritative by Distribution Point due to faulty matching logic

If a certificate had more than one distributionPoint, then only the first distributionPoint would be considered against each CRL's IssuingDistributionPoint distributionPoint, and then the certificate's subsequent distributionPoints would be ignored. The impact was that correct provided CRLs would...

CVE-2026-30836

A flaw was found in Step CA, an online certificate authority. A remote attacker can exploit this vulnerability by sending an unauthenticated SCEP Simple Certificate Enrollment Protocol Update Request. This allows the attacker to issue unauthorized certificates, potentially leading to a compromise...

CRL Distribution Point Scope Check Logic Error in AWS-LC

Summary AWS-LC is an open-source, general-purpose cryptographic library. Impact A logic error in CRL distribution point matching in AWS-LC allows a revoked certificate to bypass revocation checks during certificate validation, when the application enables CRL checking and uses partitioned CRLs wi...

GHSA-WVVQ-WGCR-9Q48 Traefik has a Potential mTLS Bypass via Fragmented TLS ClientHello Causing Pre-SNI Sniff Fallback to Default Non-mTLS TLS Config

Summary There is a potential vulnerability in Traefik's TLS SNI pre-sniffing logic related to fragmented ClientHello packets. When a TLS ClientHello is fragmented across multiple records, Traefik's SNI extraction may fail with an EOF and return an empty SNI. The TCP router then falls back to the...
