About this tag
The x/crypto vulnerability tag covers reporting on CVE-2026-39833, a flaw in the Go cryptography library’s SSH agent package before version 0.52.0. The issue involves in-memory SSH agent keyrings accepting a “confirm before use” constraint without enforcing it, weakening a security control intended to require approval before private keys are used. Coverage explains why this matters for administrators and developers: SSH agents can mediate access to servers, repositories, bastion hosts, and automation systems. Follow this tag for details about the affected component, the security implications of ignored confirmation constraints, and the recommended update to golang.org/x/crypto version 0.52.0.
