Summary
The Agent (as modeled)
CraftBot is a self-hosted personal agent that runs as a background service on its owner's own computer, plans and executes multi-step work for that single owner, and reaches the outside world through a local browser chat interface, a set of connected messaging and productivity integrations, two bundled tool servers it launches on every run, and the owner's own model provider. Untrusted material arrives from several directions at once: pages it fetches from the web, messages strangers send on the owner's connected platforms, files it reads from anywhere on the disk, and results returned by those tool servers. What it may do with that material is unusually broad — it runs commands in the host shell, reads and writes any file by absolute path, sends mail and messages from the owner's accounts, makes arbitrary web requests, and builds and publishes small local web applications. Two surfaces matter most: the host shell, which is present in every task, and the agent's own instruction and memory files, which it can rewrite and which are reloaded at the start of every future session.
Priority Threats (led by attack paths)
The pattern behind the worst of it is that the safety model is written as instructions to the model rather than as code, and three chains are open because of it. A web page the agent reads can carry text the agent acts on, and its next step can be a host command that runs with the owner's model-provider keys handed to it in the environment; nothing between the page and the shell checks anything, and the one module in the tree named for input sanitization is never called and would not block a match if it were. A result returned by one of the bundled tool servers can travel the same route into the file reader, pull stored access tokens and provider keys off disk into the conversation, and leave over an outbound request to any address on the internet, because no destination list and no approval step exist anywhere on that path. And a stranger's message on a connected platform, though it is correctly stopped from starting a task of its own, still has a few hundred characters of its text pasted into the conversation the owner sees next, from where it can direct a write into the files that define the agent's standing instructions — a change that survives every restart.
Fix the shell first: require the owner to approve a command before it runs, show them the exact command, and stop handing the process environment and the API keys in it to whatever that command starts. Then close the write path into the agent's own instruction and memory files, and put a destination list and a confirmation step in front of outbound sends and requests. Two more items belong in the same pass: the permission tiers the documentation presents as the approval mechanism for scheduled and self-initiated work are never consulted at run time, so background tasks act unsupervised, and live third-party client secrets are checked into the source, deliberately split so scanners will not spot them, which means they should be treated as already compromised and rotated. Where the team did write controls in code they are good ones — a real gate on stranger messages, a filter that blocks requests to internal addresses, action and token ceilings that stop and ask the owner, and a ledger that keeps a completed send from running twice — which is what makes the absent approval layer read as an omission rather than something beyond the project.

Attack Paths
A web page the agent reads runs commands on the owner's machine
- Fetched web content [PRAX-2026-08-12-001] Attacker-authored text on any page the agent is asked to read — unauthenticated, unlabeled provenance, and the agent has no relationship with the host serving it.
- web_fetch / web_search [PRAX-2026-08-12-001] web_fetch extracts the page text and returns it into the model context with no trust tier attached.
- AgentBase react loop [PRAX-2026-08-12-005] The react loop assembles that text into the same prompt as the owner's instructions; the only sanitizer in the tree is never called and would pass a match through anyway.
- run_shell (host command execution) [PRAX-2026-08-12-001] The next selected action executes on the host with shell=True and a full copy of the environment, handing the owner's provider API keys to whatever runs.
A bundled tool server's output sends the owner's stored tokens to a stranger's server
- Default-enabled MCP servers [PRAX-2026-08-12-009] Both enabled servers resolve an unpinned upstream package on every start, so their tool output is third-party content of unverified provenance entering the context unlabeled.
- AgentBase react loop [PRAX-2026-08-12-001] That output is folded into the prompt with no provenance separation and can direct the loop's next action.
- File read actions [PRAX-2026-08-12-006] The file reader accepts any absolute path with only an existence check, so the documented token store and the settings file are read into the conversation.
- AgentBase react loop [PRAX-2026-08-12-007] The loop chooses an outbound action with the credential text in context and nothing checks the destination or asks the owner.
- http_request (outbound HTTP) [PRAX-2026-08-12-007] A POST carries the credentials to any public host the model was steered to — the SSRF filter bounds internal addresses only, and no allowlist bounds external ones.
A stranger's message rewrites the agent's standing instructions for every future session
- Third-party platform sender [PRAX-2026-08-12-015] A non-owner sender on a connected platform — explicitly a forbidden counterparty, and attacker-authored.
- Third-party message routing gate [PRAX-2026-08-12-015] The gate stops the message opening a session but posts a notification carrying 500 characters of the sender's raw text into conversation history.
- AgentBase react loop [PRAX-2026-08-12-001] That history is replayed into the prompt on the owner's next turn, where the surrounding instructions are prompt-level only.
- File write actions [PRAX-2026-08-12-017] The write action takes the path verbatim with no containment check and no protected-path denylist.
- Session-loaded instruction files [PRAX-2026-08-12-017] The identity and manual files reloaded at the start of every session are rewritten, so the change persists across restarts with only prompt text forbidding it.

|---|---|---|---|
| T | LLM01 | Page text from web_fetch, contents returned by the file reader and output from the two bundled MCP servers are concatenated into the same prompt as the owner's instructions with no provenance label or trust tier, so an instruction planted in any of them is indistinguishable from a command. | confirmed PRAX-2026-08-12-001 |

| E | LLM03 | The model can widen its own capability set mid-task by calling add_action_sets, which is itself a core action, so the compiled per-task action list is not a boundary and no owner step stands between a task and a larger tool inventory. | confirmed PRAX-2026-08-12-003 |

lane_fit: Three strains, none forced. Fetched web content is modelled as a user_inputs entrypoint because the lane owns 'any untrusted input origin', though the remote host serving it is equally an external service. The Living UI listeners and the cloudflared tunnel sit in external_deploy as a deploy surface even though the agent starts them locally at runtime. The credential, configuration and log stores sit in external_deploy per the lane table's secrets/telemetry contents although they are ordinary local files the tools reach.
omissions: Arbitration divergences from the stored tags, KB winning: (1) PRAX-2026-08-12-008 is stored as ASI07 — Insecure Inter-Agent Communication, but a Living UI web listener exposed on 0.0.0.0 with wildcard CORS is not inter-agent communication and no other ASI or LLM category honestly names an unauthenticated network-exposed listener, so the threat is tagged null rather than forced. (2) PRAX-2026-08-12-007 is stored with LLM02 primary, but its quoted evidence is grant/gate evidence (a method allowlist, no destination allowlist, an irreversible flag that gates nothing), which the LLM KB's evidence-class rule makes LLM03 primary with LLM02 and ASI02 riding as co-tags — the value-transfer threat is therefore tagged LLM03, and LLM02 is used only where the mechanism recorded is disclosure itself. (3) PRAX-2026-08-12-003 stores ASI10 as its agentic tag; under the Agentic KB's outlive test an approval layer that is structurally absent for the agent as a whole is LLM03 primary with ASI10 as the co-tag, so both boundaries carrying it are tagged LLM03. Node-id coinage: no code object names the remote-content origin, so 'fetched web content' is taken from web_fetch's own description text; the integration sender family is named for the table that enumerates it in a leading-underscore file, whose id was formed by dropping the underscore by analogy with the contract's leading-dot rule. Edgeless nodes: the embedded credential registry (repo posture, no data flow) and the PromptSanitizer stub (no call site anywhere in the tree). Suspected but not modelled for want of a distinct trust consequence: the sub-agent spawn path and its per-sub-agent log sinks, the OAuth localhost callback server (binds 127.0.0.1 explicitly), the 195-skill corpus and 157-entry MCP catalogue that ship overwhelmingly disabled, and the Stripe integration's payment actions, which fold into the integration sender family.
