Findings (9)

HIGH
Fetch URL and use as instructions
L2891

Detects fetching external URLs and using the content as agent instructions or rules

prompts via a remote Comfy server
FIX

Sanitize or validate all external inputs (file contents, API responses, user messages) before including them in prompts or tool calls. Implement input/output boundaries between trusted and untrusted data.

FP?

Likely FP if the matched text is the skill's own instruction set describing how to handle user input, not an actual injection payload.

HIGH
Read external content and apply as rules
L3467

Detects skills that read remote markdown or documentation and apply it as operational rules

load entire Windows working web + use as context
FIX

Treat tool outputs as untrusted data. Do not act on directives found in tool responses without explicit user confirmation. Implement output validation before acting on tool results.

FP?

Likely FP if the match is a skill description explaining that it processes tool outputs, rather than a payload designed to hijack the agent via tool responses.

HIGH
Zero-width character obfuscation
L4094

Detects zero-width characters used to hide content

FIX

Remove hidden directives embedded in markdown, HTML comments, or encoded text. All agent-facing text should be explicit and visible in the skill definition.

FP?

Likely FP if the match is a standard markdown formatting pattern or HTML comment used for documentation rather than concealing directives.

HIGH
Zero-width character obfuscation
L7326

Detects zero-width characters used to hide content

FIX

Remove hidden directives embedded in markdown, HTML comments, or encoded text. All agent-facing text should be explicit and visible in the skill definition.

FP?

Likely FP if the match is a standard markdown formatting pattern or HTML comment used for documentation rather than concealing directives.

HIGH
Zero-width character obfuscation
L12690

Detects zero-width characters used to hide content

FP?

HIGH
Zero-width character obfuscation
L15922

Detects zero-width characters used to hide content

FIX

Remove hidden directives embedded in markdown, HTML comments, or encoded text. All agent-facing text should be explicit and visible in the skill definition.

FP?

Likely FP if the match is a standard markdown formatting pattern or HTML comment used for documentation rather than concealing directives.

Benign heading "'@openai/agents:*'\n;\n// Verbose logging\n..." followed by dangerous content (category: credential_access)

FIX

Ensure section headings accurately reflect the content that follows. Remove headings that could mislead an LLM into treating content differently than intended.

FP?

Likely FP if the heading mismatch is due to inconsistent markdown formatting or a benign section title that happens to contain keywords like system or config.

LOW
External API response used without validation
L94

Detects patterns where external API responses are used directly without validation or sanitization

API
Research & Data + without requiring use
FIX

Validate and sanitize all data received from external APIs before using it in tool operations or agent prompts. Implement schema validation and treat API responses as untrusted input.

FP?

Likely FP if the match is a truncated table cell or documentation fragment that mentions API responses in a descriptive context, not actual unvalidated data processing.
