CVE-2026-92701

Cocos AI (ultravioletrs) versions up to and including 0.8.2 contain a session-misbinding vulnerability in the intra-handshake attested TLS (aTLS) Intel TDX verifier path . The root cause is that the expected current-session freshness value is not copied into the TDX quote-body policy before quote...

Man-in-the-Middle Attack (MITM)

github.com/edgelesssys/constellation is vulnerable to Man-in-the-Middle Attacks MITM. The vulnerability exists because attestation user data, including the digest of a public key in a aTLS connection are incorrectly bound to the issuers TPM, not the PCR state. If an attacker can intercept a node...

GHSA-R2H5-3HGW-8J34 User data in TPM attestation vulnerable to MITM

Impact Attestation user data such as the digest of the public key in an aTLS connection was bound to the issuer's TPM, but not to its PCR state. An attacker could intercept a node initialization, initialize the node themselves, and then impersonate an uninitialized node to the validator. In...
