Security
1 high severity finding. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill includes a curl example that passes credentials on the command line (-u <user>:<password>), which would require embedding real username/password values verbatim if the agent were to execute or emit the command, creating a high secret-exfiltration risk.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The neo4j-cypher-skill runtime path ingests outsider free text via the user’s request that is used to generate Cypher (Schema-First Protocol + query generation/validation), so the workflow can be influenced by attacker-authored text without selecting any specific trusted item first.
