JLSEC-2026-723 Heap buffer overflow in CertFromX509 via AuthorityKeyIdentifier size confusion

Heap buffer overflow in CertFromX509 via AuthorityKeyIdentifier size confusion. A heap buffer overflow occurs when converting an X.509 certificate internally due to incorrect size handling of the AuthorityKeyIdentifier extension...

X.509 trust-chain bypass in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra OPENSSLEXTRA and whose application validates certificates by calling X509verifycert with caller-supplied untrusted intermediate certificates; for...

JLSEC-2026-690 A certificate verification error in wolfSSL when building with the `WOLFSSL_SYS_CA_CERTS` and...

A certificate verification error in wolfSSL when building with the WOLFSSLSYSCACERTS and WOLFSSLAPPLENATIVECERTVALIDATION options results in the wolfSSL client failing to properly verify the server certificate's domain name, allowing any certificate issued by a trusted CA to be accepted regardles...

JLSEC-2026-716 Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA...

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

JLSEC-2026-701

In wolfSSL 5.8.2 and earlier, a logic flaw existed in the TLS 1.2 server state machine implementation. The server could incorrectly accept the CertificateVerify message before the ClientKeyExchange message had been received. This issue affects wolfSSL before 5.8.4 wolfSSL 5.8.2 and earlier is...

JLSEC-2026-703

An integer overflow vulnerability existed in the static function wolfssladdtochain, that caused heap corruption when certificate data was written out of bounds of an insufficiently sized certificate buffer. wolfssladdtochain is called by these API: wolfSSLCTXaddextrachaincert,...

JLSEC-2026-738 Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA

Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA. Intermediate CA certificates are required to have the keyCertSign key usage when a Key Usage extension is present, but chain-supplied temporary CAs WOLFSSLTEMPCA added while building a certificate path were previously exempt...

JLSEC-2026-696 Certificates with wildcard DNS SANs (e.g

Certificates with wildcard DNS SANs e.g. .example.com bypassed CA name-constraint checks. A certificate with a wildcard DNS SAN that should be rejected by the issuing CA's permitted/excluded DNS name constraints could be accepted...

JLSEC-2026-735 Un-negotiated Raw Public Key (RFC 7250) accepted in place of an X.509 certificate, bypassing chain...

Un-negotiated Raw Public Key RFC 7250 accepted in place of an X.509 certificate, bypassing chain validation. A raw public key has no chain, so ParseCertRelative accepts it without performing any trust verification; it must therefore only be accepted when RPK was actually negotiated for that peer...

CVE-2026-48815

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the documented certificateOIDs option in sigstore.verify is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked and applications...

CVE-2026-48816

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.1.1, @sigstore/verify derives a transparency-log timestamp from tlogEntries.integratedTime for bundle v0.2 inclusionProof-only entries even though the inclusion proof path does not cryptographically bind...

CVE-2026-48816 sigstore-js: Insufficient Verification of Data Authenticity

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.1.1, @sigstore/verify derives a transparency-log timestamp from tlogEntries.integratedTime for bundle v0.2 inclusionProof-only entries even though the inclusion proof path does not cryptographically bind...

GHSA-CM26-5974-52H8 nebula-mesh: Certificate revocation is never enforced at the mesh

Summary nebula-mesh revokes a host by adding its certificate fingerprint to a per-CA blocklist and shipping that list to every other agent on each poll. Slack's Nebula enforces certificate revocation ONLY through the pki.blocklist list in config.yml no CRL/OCSP. The project's own code states this...

CVE-2026-48815 sigstore-js: `certificateOIDs` verification constraints are silently dropped and never enforced

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the documented certificateOIDs option in sigstore.verify is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked and applications...

GHSA-2P2F-PX33-4VV5 nebula-mesh: CA private key not zeroized on web mobile-bundle error paths

Impact The web handler renderMobileBundle internal/web/handlers.go:1325 passes the real pki.CAResolver directly into mobilebundle.Build. Inside Build internal/mobilebundle/builder.go:54, resolver.LoadByID decrypts the CA's ed25519 private key into a pki.CAManager, but Build never calls...
