Bug Name: No CAA Record Found

Vulnerability Target: https://www.zama.ai/

Vulnerability description:
If a domain does not have a Certification Authority Authorization (CAA) record in its DNS settings, it means that no Certificate Authorities (CAs) are restricted from issuing SSL/TLS certificates for that domain. This absence might raise security concerns since any CA can issue a certificate for the domain, possibly allowing hostile actors to get illegitimate certificates.

Steps to reproduce:

1. Use a [https://www.nslookup.io/caa-lookup/] for CAA Record check.
2. Enter your site (zama.ai) on nslookup.
3. You can see does not have any CAA records.

impact:
Without a CAA record, any CA can issue certificates for the domain, leading to risks of unauthorized issuance and fraudulent certificates. This vulnerability can facilitate man-in-the-middle attacks, phishing, and spoofing, compromising secure communications and tricking users. The resulting trust and reputation damage can be significant, and non-compliance with security standards may lead to legal and financial repercussions.
