RHSA-2025%3A3820 PUBLISHED CVSS 8.199999809265137 HIGH

A flaw was found in the x/crypto/ssh go library. Applications and libraries that misuse the ServerConfig.PublicKeyCallback callback may be susceptible to an authorization bypass. For example, an attacker may send public keys A and B and authenticate with A. PublicKeyCallback would be called only twice, first with A and then with B. A vulnerable application may then make authorization decisions based on key B, for which the attacker does not control the private key. The misuse of ServerConfig.PublicKeyCallback may cause an authorization bypass.
