🤖 NomShub: Weaponizing Cursor's Remote Tunnel Through Indirect Prompt Injection and Sandbox Breakout
NomShub is a critical vulnerability chain in the Cursor AI code editor where a malicious repository can silently hijack a developer's machine, combining indirect prompt injection, a sandbox escape via shell builtins, and Cursor's built-in remote tunnel to give attackers persistent, undetected shell access triggered simply by opening a repo.

🔴 Double Agents: Exposing Security Blind Spots in GCP Vertex AI
Unit 42 researchers found that GCP Vertex AI Agent Engine's default P4SA service account has excessive permissions, enabling credential theft via the metadata service. This allows privilege escalation to read all consumer GCS buckets, access restricted Google-internal Artifact Registry container images, and expose internal source code.

🔶 Cracks in the Bedrock: Bypassing SCP Enforcement with Long-Lived API Keys
Sonrai Security researcher discovered that AWS "bedrock-mantle" IAM permissions could bypass SCP enforcement when using long-lived Service Specific Credential API keys. IAM policy denials worked correctly, but SCP denials were bypassed. AWS patched this between Jan–Feb 2026; no customer action required.
