goshs: SSH host key verification disabled, allowing transparent MITM of every tunnelled HTTP request

Summary The --tunnel / -t flag opens an outbound SSH connection to localhost.run:22 with HostKeyCallback: ssh.InsecureIgnoreHostKey. The Go documentation for that function states verbatim: "It should not be used for production code." With the callback disabled the client accepts any host key the...

CVE-2026-44699

LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

CVE-2026-44714

The bitcoinj library is a Java implementation of the Bitcoin protocol. Prior to 0.17.1, ScriptExecution.correctlySpends contains two fast-path verification bugs for standard P2PKH and native P2WPKH spends in core/src/main/java/org/bitcoinj/script/ScriptExecution.java. In both branches, bitcoinj...

CVE-2026-44714

CVE-2026-44714 affects the bitcoinj Java library prior to 0.17.1. The issue lives in ScriptExecution.correctlySpends() and creates two fast-path verification bugs for P2PKH and native P2WPKH spends. In both paths, the code validates an attacker-controlled signature/public-key pair but does not ve...
