Security audit

Google Photos

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Google Photos through OOMOL, but its first-time setup tells agents to run unverified remote installer scripts directly in a shell.

Install only if you trust OOMOL and are comfortable connecting Google Photos through its service. Do not let an agent run the documented pipe-to-shell installer automatically; prefer a verified, version-pinned CLI installation path and confirm every write or destructive Photos action before it runs.

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs users to install software via curl ... | bash, which executes a remotely fetched script without prior verification. If the install endpoint, transport, hosting, or upstream release process is compromised, this can lead to arbitrary code execution on the user's machine under the user's privileges.

Finding

The description says to use this skill for "ANY Google Photos request" and "Whenever a task involves Google Photos," which is broader than a narrowly scoped activation condition. This can cause unintended invocation for casual mentions or tasks that only tangentially involve Google Photos, with no negative examples or exclusion criteria provided.
