Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill explicitly fetches and ingests public GitHub content (e.g., raw diffs and RELEASES from https://raw.githubusercontent.com and the Upgrade Helper URLs shown in SKILL.md and references/upgrade-helper-core.md) and requires the agent to read those diffs to build baselines and drive merge/install actions, so untrusted third‑party content can materially influence tool use and next steps.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly runs curl at runtime to fetch rn-diff-purge content (e.g. https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/<current_version>..<target_version>.diff and https://raw.githubusercontent.com/react-native-community/rn-diff-purge/master/RELEASES), and those fetched diffs are required and directly drive the upgrade actions/instructions the agent will follow.
