CVE-2026-46595 Invoking VerifiedPublicKeyCallback permissions skip enforcement in golang.org/x/crypto/ssh

Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped...

CVE-2026-39829 Invoking pathological RSA/DSA parameters may cause DoS in golang.org/x/crypto/ssh

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

CVE-2026-46595

CVE-2026-46595 affects golang.org/x/crypto/ssh. The issue arises when VerifiedPublicKeyCallback is invoked with a callback type other than public key, causing the source-address validation to be bypassed and enabling an authorization bypass. The description notes this is a continuation of CVE-202...

CVE-2026-46598

CVE-2026-46598: Several connected sources confirm that for certain crafted inputs, a golang.org/x/crypto/ssh/agent workflow can cast malformed wire bytes into an ed25519.PrivateKey, causing a panic when the key is used. The description is consistent across NVD, Debian, CIRCL, and OSV entries, ind...
