🔴 Analysis failures publish empty reports
When analysis throws, generateReportData returns an incomplete report instead of failing. execute publishes it as successful, replacing valid results with unusable output.
Learn more
The entire analysis and DTO-construction block shares this catch. A parser, Git-history, ranking, rendering, or unexpected runtime failure therefore becomes a DTO containing only project metadata. The generated template expects classMap, relationship sections, and classCycles, while execute serializes the partial DTO and logs successful generation.
Example: If cycle ranking throws for a repository, an existing complete refactor-first.json is atomically replaced by a metadata-only file. Maven exits successfully and the viewer cannot display the requested analysis.
Recommended fix: Let analysis failures propagate so Maven reports failure and the previous report remains intact. If missing Git history is intentionally recoverable, handle only that specific condition and return a complete error-state DTO that the template renders explicitly.

🟡 Oversized cycles show blank maps
When a cycle exceeds the threshold, initWasmGraphs skips rendering it. The template still shows its empty graph panel without a size warning.
Learn more
The report records largestCycle.dotThresholdExceeded, and initWasmGraphs deliberately skips inline rendering when it is true. Unlike the class and package sections, the cycle template neither hides the graph container nor renders the “SVG is too big” explanation.
Example: A largest cycle has 2,500 classes and 2,000 relationships. Its popups remain available, but the inline cycle-map area is only a large empty bordered rectangle.
Recommended fix: Wrap the cycle container in an inverted dotThresholdExceeded section and add the same explanatory message under the positive section. Keep popup buttons outside that condition if large graphs remain supported there.

🟥 Report data enables stored HTML injection
A crafted duplication-partner name enters content with HTML entities, then triple-brace rendering decodes it into active markup. Opening the report can execute attacker-controlled HTML.

🟨 Mutable CDN assets run without integrity checks
Versionless CDN imports and missing integrity metadata let changed third-party assets execute whenever users open generated reports.

🟡 Failed analyses expose broken map controls
When analysis fails, classMap is absent but its controls still render. Clicking either control references undefined classGraph_dot and fails.
Learn more
Failed analysis results contain only project metadata; generateReportData also uses this shape when no Git repository exists. The viewer defines classGraph_dot only when data.classMap.dot exists. The unconditional class-map section therefore exposes controls whose third argument does not exist.
Example: Run jsonReport in a directory without a Git repository. The generated report shows the analysis warning and class-map buttons. Clicking “Show classGraph 2D Popup” raises ReferenceError: classGraph_dot is not defined instead of keeping unavailable analysis controls hidden.
Recommended fix: Guard the complete class-map section with {{#classMap}}...{{/classMap}}, or build a complete empty report DTO on failure and explicitly disable graph controls.

🟡 Viewer copy failures report success
When a resource copy fails, copyViewerResources suppresses the exception. The Maven goal succeeds with a missing or stale report viewer.
Learn more
The generated JSON depends on both copied resources: index.html loads the Mustache template, and the template supplies the report markup. Suppressing a copy failure leaves a partially updated artifact set while Maven records a successful goal.
Example: If index.html already exists but replacing it fails, the JSON is updated and the warning is logged. CI still succeeds and publishes the stale viewer, which can be incompatible with the new JSON.
Recommended fix: Propagate copy failures from copyViewerResources so execute and the Maven goal fail instead of publishing partial output.

🟡 Class relationship links disappear
Each ClassRelationshipDTO receives only plain renderedLabel; its URL fields remain unset. Relationship endpoints no longer link to their source files.
Learn more
The existing HTML report creates each endpoint through renderClassEdge, which calls hyperlinkClass. The JSON DTO defines sourceUrl and targetUrl, but this builder never populates them, and renderPlainClassEdge deliberately emits text only. The Mustache relationship table consequently has no URL data to render.
Example: For com.example.A -> com.example.B, with both classes mapped to repository paths, the HTML report links A and B. The new viewer displays A → B : 1 as plain text.
Recommended fix: Populate sourceUrl and targetUrl from the source-path mapping, then render escaped endpoint links in the Mustache template rather than relying on a pre-rendered plain label.
