TL;DR: Composio’s incident shows how an attacker moved through internal monitoring, automated remediation, sandbox tool registration, and code execution, exposing roughly 5,000 GitHub OAuth grants and 5,241 cached API keys according to P0 Security. The real failure was trusted automation with standing authority, not agents behaving badly.
NHIMG editorial — based on content published by P0 Security: The Composio breach, let’s stop blaming the agents
By the numbers:
- The disclosed impact included roughly 5,000 GitHub OAuth grants.
- The disclosure said 5,241 cached API keys were likely exposed.
- The full list of leaked connections represented only 0.3% of total active connections.
Questions worth separating out
Q: What breaks when internal automation has standing privilege inside an agentic platform?
A: The boundary between observation and action breaks first, then the whole control chain becomes reusable by an attacker.
Q: Why do agentic workflows complicate least privilege for IAM teams?
A: Least privilege becomes harder when a workflow can change what it does at runtime and inherit authority across multiple internal surfaces.
Q: How should security teams govern tool registration in AI platforms?
A: They should govern it like a privileged identity event, not a normal configuration change.
Practitioner guidance
- Separate observation from remediation Ensure monitoring systems cannot directly trigger corrective actions across the same privilege boundary.
- Review tool registration as a privileged event Treat connector definitions, sandbox tool registrations, and remediation policy changes as identity events that require explicit governance.
- Map standing authority inside internal automation Inventory every internal workflow that can touch customer credentials, cached secrets, or execution environments.
What's in the full analysis
P0 Security's full article covers the operational detail this post intentionally leaves for the source:
- The breach timeline across monitoring, remediation, sandbox registration, and code execution
- The specific internal control failures that let trusted automation become an attack path
- The disclosed impact details, including exposed OAuth grants and cached API keys
- The source article’s own interpretation of how the internal architecture shaped the incident

Standing privilege, not agent intelligence, was the decisive failure in the Composio breach. The article shows that a monitoring surface, remediation surface, and execution sandbox were already connected by authority the attacker could traverse. That means the control failure was built into the privilege model before any attacker arrived. For identity governance, the practitioner conclusion is blunt: internal automation must be treated as a high-risk identity path, not as a safe implementation detail.
A few things that frame the scale:
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, according to The State of Non-Human Identity Security.
- Lack of credential rotation is cited as the top cause of NHI-related attacks by 45% of organisations, followed by inadequate monitoring and logging at 37% and over-privileged accounts at 37%.
A question worth separating out:
Q: Who is accountable when internal automation exposes customer credentials?
A: Accountability sits with the control owners who allowed the privileged workflow to exist without a stronger boundary. In practice, that spans IAM, PAM, platform engineering, and security operations because the failure is usually a shared delegation model. Strong governance means every automated action has a named owner and a bounded authority.
