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: 0.80). The skill's references/persistence.md explicitly instruct the agent to fetch and process user-generated messages via PubNub's History API (fetchMessages, initial load and catch-up patterns), which exposes it to untrusted third-party content that could carry instructions.
Where we found it
PubNub History API (ps.pubnub.com)
domain · 11 sites
The persistence.md reference file contains 10 code examples using pubnub.fetchMessages() to retrieve user-generated messages from PubNub's History API, which serves untrusted third-party content that could carry prompt-injection instructions.
PubNub Real-time API (pubsub.pubnub.com)
domain · 5 sites
The reference files contain 5 code examples using pubnub.addListener() with message handlers that process user-generated real-time messages from PubNub's subscribe API, which serves untrusted third-party content that could carry prompt-injection instructions.
