TL;DR

Affected versions of this package contain a low-severity issue in verify that could allow signatures generated by an attacker with access to a secret key to be accepted as valid for any message under that same key, weakening message-binding guarantees and primarily impacting systems that rely on non-repudiation. An attacker who obtains or controls a secret key could exploit this flaw by producing a signature once and reusing it to falsely assert authenticity over different messages, potentially undermining auditability, proof of origin, and trust in signed records.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
