Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Handshake verification previously relied on mock validations or omitted signature checks entirely, allowing arbitrary unauthenticated agents to establish trust. The fix enforces Ed25519 signature checks tied to the Identity Registry.
Dependency Confusion: Multiple components and installer configurations suffered from dependency confusion risks by referencing unregistered and placeholder PyPI package names. Attackers could register these on the public index to achieve arbitrary code execution.
Path Traversal: Directory traversal vulnerabilities existed across plugin installers and the sandbox environment due to inadequate path canonicalization and verification. The fixes enforce strict resolution limits within authorized roots.
