๐Ÿญ Your Agent Is The Attack Surface ๐Ÿ’€

Trusted Tools Turn Treacherous

Sponsored by

Good morning. The intern asked his coding agent to fix a Sentry error this morning. Twenty minutes later, his AWS keys were in someone else's inbox.

He didnโ€™t even clicked anything.

Letโ€™s dive in ๐Ÿ‘‡

๐Ÿญ Whatโ€™s Cookinโ€™:

  • A fake bug report can hijack Claude Code, Cursor, and Codex now

  • Visa plugged its payment network into ChatGPT so agents can shop for you

  • Oracle stacked a $638B AI backlog and the stock still fell

๐Ÿ”“ Your Agent Is The Attack Surface

The Bite:

Tenet Security disclosed a new attack class called Agentjacking on June 12.

The technique uses a fake Sentry error report to trick AI coding agents into executing malicious code on developers' machines.

It requires no malware, no stolen credentials, and no breach of the target.

Sentry's public DSN keys sit openly in website source code by design, so anyone can send a crafted error report to a project via API.

The fake error includes a hidden "Resolution" section containing a command, formatted to look like Sentry's own remediation advice.

Coding agents read Sentry through MCP, treat the response as trusted, and execute the payload when a developer asks them to fix unresolved errors.

Snacks:

  • Tenet found 2,388 organizations exposed, from a $250B enterprise to solo developers and one cloud-security vendor

  • A single injected error can reach environment variables, AWS keys, GitHub tokens, and git credentials

  • The attack bypasses EDR, firewalls, IAM, and VPNs because nothing in the chain is technically unauthorized

  • Agents ran the attacker's code even when explicitly prompted to ignore untrusted data

  • Tenet disclosed to Sentry on June 3, Sentry acknowledged but called the root cause "technically not defensible"

  • Sentry shipped a filter for one specific payload string rather than addressing the trust model

Why it Bites:

Every tool your coding agent connects to through MCP is now a potential entry point because the agent treats their output as trusted by default.

Sentry working exactly as designed is the vulnerability itself.
DSN keys are public. Error submission is open.

The agent reads what Sentry returns, and acts on it.
That's MCP doing its job.

The weakest link used to be the developer clicking the wrong attachment or running an unvetted script. Now it's the agent.

Because it doesn't hesitate, it doesn't hover over the command, and it doesn't get a bad feeling. It executes with your credentials because that's what you asked it to do.

Sentry's response says everything about where this goes.

They called the root cause "technically not defensible" and shipped a string filter for one payload. Itโ€™s a shrug with a commit message.

The same attack works through any tool that accepts public input and feeds it to an agent. Support tickets, GitHub issues, documentation pages.

Every MCP connector is a door, and right now every door is unlocked from the outside.

And thatโ€™s why you should review your task scope before pressing โ€˜Enterโ€™.
