Miggo AIRoot Cause Analysis

The provided vulnerability information describes a stored XSS in the Knowledge Base label handling, but no specific code snippets, commit diffs, or implementation details are available. While the root cause is clearly missing input sanitization/output encoding when processing user-supplied KB labels, the exact PHP functions responsible for (1) storing KB labels in the database or (2) rendering them in HTML templates cannot be identified with high confidence without access to the actual TeamPass codebase structure from version 2.1.27.36. The advisory and issue thread don't provide enough implementation-level details to pinpoint specific functions.
