In this article 1. Real-world scenarios 2. Best Practices: Identity + RBAC + Scope + Safe Tool Binding 3. Looking Ahead AI agents aren't only smarter API callers. They plan, chain actions across systems, and invoke tools in sequences while no single human explicitly approves each step. The...

golang.org/x/crypto/ssh/agent: golang.org/x/crypto/ssh/agent: Security bypass due to improper handling of key restrictions

A flaw was found in golang.org/x/crypto/ssh/agent. When a key was added to a remote agent, security restrictions, known as constraint extensions, were not properly processed during the request. This allowed these restrictions to be silently removed when keys were forwarded, leading to the...

crypto/x509: Incorrect enforcement of email constraints in crypto/x509

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly...

USN-8551-1 tomcat8 vulnerabilities

It was discovered that Tomcat incorrectly handled authorization when multiple method constraints defined the same HTTP method. A remote attacker could possibly use this issue to bypass authorization restrictions. CVE-2026-43515 It was discovered that the Tomcat number guess example application di...

erlang: Erlang OTP public_key: Certificate validation bypass allows hostname spoofing

A flaw was found in Erlang OTP publickey. This improper certificate validation vulnerability allows a subordinate Certificate Authority CA with restricted DNS nameConstraints to bypass these restrictions. By issuing a leaf certificate that lacks a Subject Alternative Name SAN but contains a craft...
