What is Prowler?

Prowler is turning its scanner into an agent that acts — and putting it behind the subscription.

Prowler still ships an open-source multi-cloud security scanner, but the last six releases have been about Lighthouse AI, its in-product agent, and the MCP server that feeds it. Lighthouse went from read-only Q&A to executing scans and managing providers, and now carries page context and reaches every tool family the MCP server advertises. Alongside that, 5.34.0 redrew the product line: CLI, Local Server, Local Dashboard and Hub stay free, while Cloud, Private Cloud and Lighthouse carry a subscription note on nearly every new feature.

What is Nautobot?

A security advisory cycle forced Nautobot to break its REST API on both supported branches at once.

3.2.0 and 2.4.38 shipped the same day in late July carrying CVE fixes that the notes state introduce breaking changes, most often surfacing as unexpected TypeError, AttributeError or KeyError for REST and GraphQL clients. The central change, from advisory GHSA-h8rv-c7c8-cvmx, is that the REST API now enforces object-level view permissions when traversing to related objects via ?depth — beyond depth 1 a related object the caller cannot view is reduced to id, object_type, url and display instead of being serialised in full. 3.2.0 also makes job_kwargs required for create_schedule, enqueue_job, execute_job and run_job_for_testing, with a temporary fallback that warns. 3.1.8 closed an authorization bypass letting a user self-approve a workflow, and 2.4.37 fixed stored XSS in Relationship and Module Family fields.

Prowler is turning its scanner into an agent that acts — and putting it behind the subscription.

◆ Current state

Prowler still ships an open-source multi-cloud security scanner, but the last six releases have been about Lighthouse AI, its in-product agent, and the MCP server that feeds it. Lighthouse went from read-only Q&A to executing scans and managing providers, and now carries page context and reaches every tool family the MCP server advertises. Alongside that, 5.34.0 redrew the product line: CLI, Local Server, Local Dashboard and Hub stay free, while Cloud, Private Cloud and Lighthouse carry a subscription note on nearly every new feature.

◆ Where it's heading

The direction is a control plane, not a scanner. Prowler MCP is becoming the real API surface — integrations, users and roles are now agent-manageable on both Cloud and the self-hosted server, with RBAC as the only guardrail. Enterprise consolidation plumbing is arriving at the same cadence as the AI work: multi-domain SAML, Compliance Watchlist and Cross-Provider Compliance all target the org juggling many tenants and frameworks. The patch releases in between are dominated by container CVE reduction and correctness fixes in M365 and Attack Paths.

◆ Prediction

The admin surfaces not yet wired to MCP are the obvious next additions — compliance framework selection and the watchlist itself, given every other section of the app has been connected in sequence over the last four releases.

5.0

A security advisory cycle forced Nautobot to break its REST API on both supported branches at once.

◆ Current state

3.2.0 and 2.4.38 shipped the same day in late July carrying CVE fixes that the notes state introduce breaking changes, most often surfacing as unexpected TypeError, AttributeError or KeyError for REST and GraphQL clients. The central change, from advisory GHSA-h8rv-c7c8-cvmx, is that the REST API now enforces object-level view permissions when traversing to related objects via ?depth — beyond depth 1 a related object the caller cannot view is reduced to id, object_type, url and display instead of being serialised in full. 3.2.0 also makes job_kwargs required for create_schedule, enqueue_job, execute_job and run_job_for_testing, with a temporary fallback that warns. 3.1.8 closed an authorization bypass letting a user self-approve a workflow, and 2.4.37 fixed stored XSS in Relationship and Module Family fields.

◆ Where it's heading

Nautobot is running two supported lines in parallel and treating them as equals: 3.2.2 and 2.4.39 both shipped on 3 August with the same many-to-many change-logging fix. The security work in this window is not incidental — the advisories cluster around authorization boundaries that the API had been permissive about, and closing them meant accepting a compatibility break rather than preserving behaviour. The documentation change acknowledging that managing a Git repository grants arbitrary code execution on the worker is the same instinct applied to expectations rather than code.

◆ Prediction

The job_kwargs fallback is explicitly temporary and warns when used, so its removal in a later release is the stated next step. Expect the paired 2.4.z and 3.x releases to continue landing together.
