Security audit

hyperframes

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent HyperFrames video workflow, but it can refresh agent skills and upgrade project dependencies from remote packages during normal use without clear user approval.

Install only if you are comfortable with HyperFrames running npm-based CLI commands, updating/installing related workflow skills, writing project files, and potentially upgrading the project's HyperFrames pin. Prefer plugin-managed installs or exact pinned versions, and review any dependency or skill update before allowing it in sensitive projects.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (103)

Hidden Instructions

High

Category: Prompt Injection
Confidence: 70% confidence
Finding: Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.
Content: Scanner excerpt · SKILL.md (reported line 40)May include surrounding context.
md
| No brief, but `hyperframes.json` or `STORYBOARD.md` exists | Resume from project files and recorded preferences. Infer the owning workflow from existing artifacts. If it cannot be determined uniquely, ask one routing-only question; do not run the intent interview. | | Fresh creation | Run the intent layer — `references/intent-interview.md` — then route once using § 2's table. |  When you edit an existing project, bracket your edits with project history (`/hyperframes-cli`, Project history in your turn).

Anti-Refusal Statement

High

Category: Anti-Refusal
Confidence: 80% confidence
Finding: 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.
Content: Scanner excerpt · SKILL.md (reported line 50)May include surrounding context.
md
A scaffolded project pins `hyperframes@<version>` in its `package.json` scripts so renders stay reproducible; the pin never advances on its own, and a pinned run of an older CLI prints no warning about it. When resuming a project whose scripts carry a pin, probe once before the first render-affecting command:

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 92% confidence
Finding: The skill invokes environment-dependent commands and external tooling but declares no explicit tool scope or permissions boundary. That creates ambiguity about what the agent is allowed to access and increases the chance of unintended environment exposure or broader-than-necessary execution when the skill is loaded.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill describes itself as a mandatory entry point for a very broad set of common creative tasks, which can cause the agent to invoke it in many situations beyond a narrow, least-privilege scope. In combination with install/update/run instructions, that broad trigger surface increases the chance of unintended tool execution and over-routing into this skill.
Content: No source excerpt is available for this finding.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 97% confidence
Finding: The skill instructs execution of npx hyperframes without pinning an exact version, which permits fetching whatever package version is current at runtime. This creates a supply-chain risk: a compromised upstream release or unexpected breaking change could alter agent behavior or execute malicious code.
Content: No source excerpt is available for this finding.

Whitespace Padding

Medium

Category: Prompt Injection
Confidence: 70% confidence
Finding: Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 97% confidence
Finding: This command uses unpinned npx hyperframes, allowing runtime resolution of the latest package rather than a reviewed version. In an agent skill, that means the execution path can change after publication and can be hijacked through the package distribution channel.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 91% confidence
Finding: The skill directs the agent to autonomously apply upgrades, verify them, revert on failure, and 'act on the signal rather than relaying it to the user.' That removes user approval from a state-changing dependency-management action, increasing the risk of unauthorized project mutation and making any supply-chain issue more dangerous in context.

npx hyperframes@latest upgrade --project . --check

text
The probe is read-only and reports the pin against the latest release; keep the explicit `.` — on older CLI releases a bare `--project` followed by another flag consumes that flag as its directory value. When it reports the project behind — or any CLI output already shows it (the stderr notice `This project pins hyperframes@… (latest …)`, or `_meta.updateAvailable: true` in a `--json` result from a pinned script) — apply with `npx hyperframes@latest upgrade --project .`, then verify with `npx hyperframes check`. A passing check confirms the project's compositions still validate on the new version — not that rendered output is frame-identical to the old pin — so a successful bump is never silent: name the old and new version in the run's summary. A project with no composition yet needs no verification. If the check fails, revert the `package.json` change, continue on the pinned version, and report which version the project stays on and why. Act on the signal rather than relaying it to the user; never leave a bumped pin unverified. ## 2. Route fresh creation

Rp1

Medium

Category: MCP Rug Pull
Confidence: 95% confidence
Finding: The skill directs automatic upgrade using npx hyperframes@latest upgrade --project ., which fetches and executes the latest published package without pinning. Because this is a mutating operation on project files, compromise of the package or an unsafe release could directly alter code and workflow outputs.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 96% confidence
Finding: The workflow installation command npx hyperframes skills update <workflow-name> relies on an unpinned remote package at execution time. Since it controls skill installation and refresh, a malicious or unexpected upstream package could modify the agent's operating instructions or install compromised workflow content.
