NVD Description

Note: Versions mentioned in the description apply only to the upstream caddy package and not the caddy package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Nebula is a scalable overlay networking tool. In versions from 1.7.0 to 1.10.2, when using P256 certificates (which is not the default configuration), it is possible to evade a blocklist entry created against the fingerprint of a certificate by using ECDSA Signature Malleability to use a copy of the certificate with a different fingerprint. This issue has been patched in version 1.10.3.
