CVE-2026-40097

A flaw was found in Step CA, an online certificate authority. A remote attacker can trigger a Denial of Service DoS by sending a specially crafted attestation key AK certificate with an empty Extended Key Usage EKU extension during Trusted Platform Module TPM device attestation. This causes an...

CVE-2026-33810

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

BIT-GOLANG-2026-33810 Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

BIT-GOLANG-2026-32281 Inefficient policy validation in crypto/x509

Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

SUSE CVE-2026-34580

Botan is a C++ cryptography library. In 3.11.0, the function CertificateStore::certificateknown had a misleading name; it would return true if any certificate in the store had a DN and subject key identifier, if set matching that of the argument. It did not check that the cert it found and the ce...

GHSA-9QQ8-CGCV-QMC9 Step CA affected by an index out of bounds panic in TPM attestation EKU validation

Summary An attacker can trigger an index out-of-bounds panic in Step CA by sending a crafted attestation key AK certificate with an empty Extended Key Usage EKU extension during TPM device attestation. Details When processing a device-attest-01 ACME challenge using TPM attestation, Step CA...

CVE-2026-40097

Step CA is an online certificate authority for secure, automated certificate management for DevOps.

CVE-2026-35656

OpenClaw is affected pre-2026.3.22 by an authentication bypass in X-Forwarded-For header processing when trustedProxies is configured, enabling an attacker to spoof loopback hops and bypass canvas authentication and rate-limiting protections by forging forwarding headers. The issue impacts the au...

CVE-2026-34477 Apache Log4j Core: verifyHostName attribute silently ignored in TLS configuration, allowing hostname verification bypass

The fix for CVE-2025-68161 https://logging.apache.org/security.htmlCVE-2025-68161 was incomplete: it addressed hostname verification only when enabled via the log4j2.sslVerifyHostName https://logging.apache.org/log4j/2.x/manual/systemproperties.htmllog4j2.sslVerifyHostName system property, but no...
