Analysis summary

Refact.ai is a community-maintained IDE extension from Refact.ai. Anomity scores its risk at 100 out of 100 (critical). It matches 3 dangerous capability combinations.

Refact.ai is an open-source AI coding assistant offering completion, chat, and an agent mode, with a self-hosted server option so the models can run inside your own infrastructure.

In self-hosted mode it reads and writes the workspace and executes commands in agent mode without sending code to a third party. The catalogued capabilities reflect the agentic configuration — filesystem read and write plus shell execution, with network access to whichever model endpoint is configured. Self-hosting removes the data-residency question but not the agent question: an agent that can edit and execute locally is still an agent that can edit and execute.

Why this entry scored 100 out of 100

This profile starts at the catalog's neutral base of 50. Because the entry is community-maintained, trust adjusts the score by -10. Declared high-risk capabilities add +20 (capped at +30). It matches 3 dangerous capability combinations, which contribute additional severity weight. The clamped result is 100, placing it in the critical band.

Findings

  • Established community project Trust offset
    Contribution to score: -10
  • 2 high-risk capabilities: filesystem:write, shell:execute Critical
    Contribution to score: +20
  • Data exfiltration risk (high) High
    Evidence
    Shell execution combined with outbound network access can exfiltrate arbitrary data from the machine.
    Contribution to score: +15
  • Persistence + execution risk (medium) Medium
    Evidence
    Shell execution plus filesystem write means the agent can plant persistent backdoors (e.g. modifying startup scripts).
    Contribution to score: +5
  • Full-control risk (critical) Critical
    Evidence
    Shell + filesystem write + network is effectively a remote shell on the employee machine.
    Contribution to score: +25

Capabilities

Every capability the entry declares, with the security implication of each.

  • filesystem:read Filesystem read
    Can read files on the host system. Used for context, indexing, or analysis.
  • filesystem:write Filesystem write
    Can create, edit, or delete files on the host system. High-impact capability — anything from helpful edits to planting persistence.
  • shell:execute Shell execution
    Can run arbitrary shell commands. Combined with network access this becomes effectively a remote shell.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.

Dangerous combinations matched

Capability pairings that compound into well-known attack patterns.

  • Data exfiltration risk high
    Shell execution combined with outbound network access can exfiltrate arbitrary data from the machine.
    shell:execute network:outbound
  • Persistence + execution risk medium
    Shell execution plus filesystem write means the agent can plant persistent backdoors (e.g. modifying startup scripts).
    shell:execute filesystem:write
  • Full-control risk critical
    Shell + filesystem write + network is effectively a remote shell on the employee machine.
    shell:execute filesystem:write network:outbound
