This vulnerability has a CVSS 3.1 base score of 2.7, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously could respond as ECDSA P256 being the accepted signature algorithm and the connection would continue with using ECDSA P256, if the client supports ECDSA P256.
Remediation
Check the references section for vendor advisories and patches from wolfssl. Update wolfssl to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
