Miggo AIRoot Cause Analysis

  1. All vulnerability descriptions explicitly mention the getcolor function in utils.py as the source of ReDoS.
  2. The PoC demonstrates exploitation through color parameter manipulation handled by this function.
  3. CWE-1333 directly implicates regex inefficiency in color parsing logic.
  4. No other functions are referenced in advisories or PoC details. The path normalization matches Python package structure (xhtml2pdf/util.py).
