GHSA-PRXJ-3GCV-CQRH
Vulnerability from github – Published: 2026-04-01 23:01 – Updated: 2026-04-01 23:01Summary
A vulnerability in vehicle authentication allows threat actor with valid client credentials (i.e., a private key and certificate from a rooted infotainment system) to impersonate arbitrary VINs when authenticating to the telemetry server.
Impact
The attacker would be able to submit falsified telemetry records for arbitrary VINs.

Mitigation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
