BrainDB

• Outcome: Review
• Latest audit: Sep 10, 2026 · 7:46 PM UTC
• Version: 0.5.2

Overview

This memory skill fits its stated purpose in part, but it needs Review because it can expose and alter long-term memories through under-disclosed external Gemini calls, broad local environment capture, and weakly protected local services.

Review this carefully before installing. Use it only if you are comfortable with a persistent memory service that can store personal and business context, modify OpenClaw configuration, run Docker services, and potentially send memory/query/conversation data to Gemini when a key is present. Prefer a local-only configuration with authentication enabled, do not run the execution-awareness encoder until you inspect its proposed memories, and verify the release artifact before running install scripts.

A.I.G

Vulnerability Patterns

• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection

Setup Executes the Contents of an Existing .env File as Shell Code

Content

View full analysis

.env echo "📋 Created .env with auto-generated Neo4j password" fi # Source .env for port variables set -a; source .env 2>/dev/null || true; set +a ``` ### Technical Analysis An environment file is expected to contain passive key/value configuration, but `source .env` instructs Bash to parse it as executable shell code. Command substitutions, function definitions, redirections, and arbitrary shell statements in an existing `.env` therefore run immediately. Suppressing errors and continuing with `|| true` does not limit execution. It may instead conceal indicators that the file contained unexpected syntax. ### Attack Path 1. An attacker modifies or plants `.env` in the project directory. 2. The file contains a payload such as a command substitution or standalone shell command. 3. The user runs `setup.sh`. 4. Bash sources `.env` and executes the payload with the user's privileges. 5. Setup continues, potentially hiding the compromise among normal Docker operations. ### Impact Assessment The payload gains all filesystem, process, credential, Docker, and network privileges available to the invoking user. Membership in the Docker group can effectively provide host-level control, making exploitation especially consequential. ]]>

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The script performs broad host introspection far beyond a narrowly scoped 'persistent semantic memory' function: it enumerates installed CLI tools, user and workspace scripts, installed skills, and fleet metadata. This creates an unnecessary inventory of the local environment that can expose sensitive operational details and expands the blast radius if the BrainDB endpoint is compromised or misconfigured.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The script reads arbitrary files from ~/bin and the workspace scripts directory, extracting content and paths to encode into memory. This can disclose private script names, internal tooling, filesystem layout, and embedded comments that may contain operational secrets or sensitive business context, none of which is necessary for core memory persistence.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

Harvesting installed skill metadata and fleet node information creates an internal capability map of the environment, including available skills and remote infrastructure. Such inventory data is highly useful for follow-on abuse because it reveals what systems exist, where they are located, and which mechanisms can be used to act on them.

Content

No source excerpt is available for this finding.

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The Gemini routing stage sends user queries together with candidate memory snippets to an external provider without visible disclosure. Because candidate snippets come from long-term memory, this can leak previously stored sensitive facts, preferences, relationships, or business information during normal recall operations.

Content

No source excerpt is available for this finding.

Ssd 3

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The prompt explicitly instructs Gemini to predict follow-up questions about a person's preferences, relationships, business specifics, and personal details from recent queries. This is deliberate sensitive-data inference and profiling, which is especially dangerous in a persistent memory system because the outputs can drive further caching, retrieval, and exposure of private information.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The auto-encode endpoint sends raw user and agent conversation content to Gemini for long-term memory distillation. Because the prompt explicitly asks for user-specific personal, business, relationship, and preference details, sensitive data can be disclosed to a third party and then persisted indefinitely, compounding privacy and compliance risk.

Content

No source excerpt is available for this finding.

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

This code transmits user and agent messages to external Gemini APIs for memory extraction, but there is no visible notice, consent flow, or user-facing disclosure in this file. In a memory product handling long-term personal data, undisclosed third-party processing materially increases privacy, legal, and trust risk.

Content

No source excerpt is available for this finding.

Ssd 3

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The auto-encoding prompt instructs the model to retain long-term personal and business details such as family, schedule, clients, pricing, and pet peeves. This is a direct mechanism for building a persistent dossier of sensitive user information, with both external transmission and durable local storage, making the memory-skill context significantly more dangerous.

Content

No source excerpt is available for this finding.

Ssd 3

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The session-context endpoint persists recent user messages, active tasks, pending questions, decisions, and summaries into memory. In a long-term memory system, this creates a high risk of storing raw conversational and behavioral data that may contain secrets, personal information, or sensitive operational details beyond what is necessary for compaction-proof context.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The optional Swarm mode sends workspace-derived content to another service for extraction, creating a clear external data-transfer path for potentially sensitive local documents. In this skill context, that is especially risky because the source material includes personal memory files and operational notes, and the manifest does not make third-party processing a primary expected behavior.
