CVE-2025-4658 (GCVE-0-2025-4658)

Vulnerability from cvelistv5 – Published: 2025-05-13 16:33 – Updated: 2025-05-13 20:11
VLAI?
Summary
Versions of OpenPubkey library prior to 0.10.0 contained a vulnerability that would allow a specially crafted JWS to bypass signature verification. As OPKSSH depends on the OpenPubkey library for authentication, this vulnerability in OpenPubkey also applies to OPKSSH versions prior to 0.5.0 and would allow an attacker to bypass OPKSSH authentication.
Severity ?
9.3 (Critical)
