This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Ghidra before 12.1 contains an authentication bypass vulnerability in PKIAuthenticationModule.authenticate() that allows any user with a valid CA-signed certificate to impersonate other users by presenting their public certificate with a null signature. Attackers can escalate privileges, modify repository access controls, exfiltrate shared reverse engineering databases, and permanently compromise server integrity.
