Hi, The following certificates appear to be misissued: https://crt.sh/?id=77893170&opt=cablint https://crt.sh/?id=77947625&opt=cablint https://crt.sh/?id=78102129&opt=cablint https://crt.sh/?id=92235995&opt=cablint https://crt.sh/?id=92235998&opt=cablint All of these certificates have a pathLenConstraint value with CA:FALSE, this violates 4.2.1.9 of RFC 5280: CAs MUST NOT include the pathLenConstraint field unless the cA boolean is asserted and the key usage extension asserts the keyCertSign bit.
