Grafana Lens

• Outcome: Review
• Latest audit: Sep 11, 2026 · 7:14 AM UTC
• Version: 0.5.0

Overview

Grafana Lens appears to be a real Grafana management and observability skill, but it defaults to exporting sensitive conversation content and gives the agent broad Grafana and optional Alloy mutation authority.

Install only if you are comfortable giving this skill Grafana service-account authority and sending agent telemetry to your configured OTLP backend. Before using it in a shared, cloud, or sensitive environment, set otlp.captureContent=false and strongly consider otlp.forwardAppLogs=false, otlp.logs=false, or otlp.traces=false until the first-message redaction bypass is fixed. Use a least-privilege Grafana token, restrict the OTLP endpoint to a trusted collector, and enable Alloy only with a tightly controlled config directory after reviewing any raw pipeline configs and delete actions.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• 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
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

{ const pending = alertStore.getPendingAlerts(); if (pending.length === 0) return; const summary = pending .map( (a) => `- [${a.status.toUpperCase()}] ${a.title} (${new Date(a.receivedAt).toISOString()})`, ) .join("\n"); return { prependContext: `GRAFANA ALERTS (${pending.length} pending):\n${summary}\nUse grafana_check_alerts to see details, then investigate with grafana_query.\n`, }; }); ``` ### Technical Analysis The webhook validates only that `status` exists and `alerts` is an array. It does not validate the type, length, character set, or semantic safety of `notification.title`. The title is stored and later interpolated verbatim into `prependContext` before the agent starts. This places externally influenced text next to direct instructions such as “Use grafana_check_alerts,” without clearly separating it as untrusted data. Gateway authentication reduces unauthenticated network exposure but does not establish that the alert title is safe ...[truncated 1635 chars]

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 91% confidence

Finding

If the implementation only exports telemetry and does not provide the documented Grafana-side operations, that is still security-relevant because reviewers may approve it as an operational dashboard tool while it actually performs background data export. The danger is deceptive capability framing that can hide outbound telemetry behavior and cause inappropriate trust or permissions.

Vague Triggers

High

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

Finding

The trigger list is extremely broad, including generic terms like investigate, debug, triage, root cause, security check, and monitoring-related phrases. In a skill with powerful read/write Grafana and pipeline-management actions, overbroad activation increases the chance of unintended invocation, exposing sensitive observability data or causing unapproved state changes.

Memory Manipulation

High

• Category: Memory Poisoning
• Confidence: 90% confidence

Finding

Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

Anti-Refusal Statement

• Category: Anti-Refusal
• Confidence: 80% confidence

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Context-Inappropriate Capability

High

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

Finding

The code enables capture of prompts, system prompts, assistant completions, and message bodies into logs and spans via prepareContent() and captureContent defaults. In a Grafana tool skill, this is over-collection: secrets, credentials, internal data, or user-sensitive business content could be exported to telemetry backends where many operators may access it.

Content

No source excerpt is available for this finding.

Context Leakage

High

• Category: Data Exfiltration
• Confidence: 85% confidence

Finding

Code or instructions that leak agent conversation context to external services, potentially exposing sensitive user interactions.

Content

ts

}

    // Record session duration + completion outcome metrics
    instruments.sessionDurationMs.record(durationMs);
    instruments.sessionsCompleted.add(1, { outcome: errorMsg ? "error" : "success" });

Ssd 3

High

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

Finding

The telemetry pipeline captures plain-language prompts, system prompts, message content, assistant completions, and tool payloads, creating a direct exfiltration path for sensitive data into logs and traces. Redaction helps but is not a reliable control for all secrets or proprietary content, and observability backends often have broader access than the primary application.

Content

No source excerpt is available for this finding.

Credential Access

High

• Category: Privilege Escalation
• Confidence: 70% confidence

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
