Review Change Stack

📝 Walkthrough

Walkthrough

The changes harden repository URL handling, HTML output, report directory resolution, and report-file writes. Maven report goals use the new containment helper. Cost-benefit analysis improves class-to-source path resolution. Tests and a 13-finding security implementation plan were added.

Changes

Report security hardening

Layer / File(s) Summary
Repository URL validation and coverage
change-proneness-ranker/src/main/java/org/hjug/git/GitLogReader.java, change-proneness-ranker/src/test/java/org/hjug/git/GitLogReaderGetRepoUrlTest.java
getRepoUrl() rejects non-HTTP(S) origins, sanitizes URL characters, and preserves valid repository path generation.
Contained and symlink-safe report output
report/src/main/java/org/hjug/refactorfirst/report/ReportWriter.java, refactor-first-maven-plugin/src/main/java/org/hjug/mavenreport/*, report/src/test/java/org/hjug/refactorfirst/report/ReportWriterTest.java
Report directories are resolved under the project base directory. Report writes reject directory and file symbolic links. Maven report goals use the containment helper.
HTML output escaping
report/src/main/java/org/hjug/refactorfirst/report/SimpleHtmlReport.java, report/src/test/java/org/hjug/refactorfirst/report/HtmlReportTest.java
Repository links, file names, project names, and versions are escaped before HTML output.
OpenVuln remediation plan
plans/openvuln-refactorfirst-RefactorFirst-full-9-2-2026-implementation-plan.md
The plan defines implementation tasks, tests, fixtures, dependencies, and validation for 13 security findings.

Disharmony source-path resolution

Layer / File(s) Summary
Class mapping and URI resolution
cost-benefit-calculator/src/main/java/org/hjug/cbc/CostBenefitCalculator.java
Disharmony paths use class mappings with an outer-class fallback. Absolute, alternative, and relative file: URI forms are handled explicitly.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to dc27b

The PR can still produce incorrect SCM results, silently omit reports, expose credentials, write outside the intended directory, generate unsafe reports, and fail under standard Maven configuration. These issues should be fixed before merge.

Inline comments:
In
`@change-proneness-ranker/src/test/java/org/hjug/git/GitLogReaderGetRepoUrlTest.java`:
- Around line 161-172: Update the test around GitLogReader.getRepoUrl to
configure the origin URL directly in Git config with a quote and an angle
bracket, then assert the returned URL contains neither disallowed character.
Ensure the input exercises the sanitization branch instead of already matching
the allowlist.

In
`@cost-benefit-calculator/src/main/java/org/hjug/cbc/CostBenefitCalculator.java`:
- Line 474: The URI-prefix construction in the repository path conversion must
handle absolute Unix paths without producing an extra slash. Update the
surrounding URI conversion method to use Path/URI relativization or correctly
construct the file URI, and add a regression test covering repositoryPath
“/tmp/repo” and “file:///tmp/repo/src/Foo.java” returning “src/Foo.java”.

In
`@plans/openvuln-refactorfirst-RefactorFirst-full-9-2-2026-implementation-plan.md`:
- Around line 449-455: Apply ReportWriter.containReportDirectory using the CLI
project base directory and outputDirectory before ReportCommand dispatches to
any of the four report executors, preferably at their shared writer or executor
boundary. Ensure CLI output paths are normalized and contained, including
symlink traversal cases, and add tests covering traversal and symlink escapes.
- Around line 373-382: Define a single canonical sanitizeCsvCell(String value)
encoder and use it for every CSV cell, including projectName, projectVersion,
fallback rows, and all values emitted by addsRow(). Remove or consolidate any
duplicate helper logic so formula neutralization and quote escaping occur
consistently without double escaping.
- Line 264: Update ReportWriter.writeReportToDisk and ReportCommand.call so
symlink-blocked report writes propagate failure instead of returning success;
use a nonzero command status or controlled exception, ensure Maven mojos receive
the failure, and add coverage asserting the command result for a blocked write.
- Around line 51-55: Update GitLogReader.getRepoUrl() to reject HTTP(S)
repository URLs containing URI user-info such as embedded credentials, returning
an empty string for those inputs; add a regression test covering this case while
preserving valid credential-free URLs.
- Around line 327-338: Update buildPackageGraphDot and its
renderPackageGraphEdge, renderPackageVertices, and renderClassVertices paths to
use separate context-specific encoders: a stable collision-resistant DOT node-ID
encoder that handles leading digits and collisions, complete DOT quoted-string
escaping, and JavaScript/raw-script escaping for values embedded in the script
template. Add coverage for </script>, backslashes, leading-digit identifiers,
and colliding package names.
- Around line 291-297: Update escapeJavaScriptString and its use in
generateBubbleChartData so file names cannot terminate the inline script
context: encode less-than and greater-than characters as JavaScript Unicode
escapes in addition to the existing escaping. Add a regression test covering a
file name containing a script-closing sequence.
- Around line 261-265: Revise the fix plan to protect every path component, not
only outputDir and reportFile: validate or create each ancestor without
following symbolic links, then perform the report write atomically with
no-follow semantics to prevent link-swap races. Extend tests to cover nested
symlinked ancestors and replacing a path component with a link during writing,
while preserving early error logging and return behavior.
- Around line 228-235: Update renderClassCycleVisuals() to derive a separate
non-empty cycle identifier for generateGraphButtons(), ensuring sanitization
prevents a leading digit before it is used in the JavaScript const name.
Preserve the HTML-escaped original cycle name for visible popup/button text, and
add coverage for empty and leading-digit names.

In
`@refactor-first-maven-plugin/src/main/java/org/hjug/mavenreport/RefactorFirstHtmlReport.java`:
- Around line 72-73: Resolve Maven’s effective reporting output directory before
calling ReportWriter.containReportDirectory, handling both absent reporting
configuration and absent outputDirectory so Maven’s
${project.build.directory}/site is used. Apply this at
RefactorFirstHtmlReport.java lines 72-73, RefactorFirstMavenCsvReport.java lines
44-45, RefactorFirstMavenJsonReport.java lines 33-34, and
RefactorFirstSimpleHtmlReport.java lines 72-73, and add goal-level tests
covering both defaults.

In `@report/src/main/java/org/hjug/refactorfirst/report/ReportWriter.java`:
- Line 43: Update the output-directory validation around ReportWriter to reject
symbolic links in every path component, not only the final reportOutputDir
entry; use component-by-component validation and descriptor-relative operations
such as SecureDirectoryStream where supported before creating directories or
writing reports, and add a regression test covering an intermediate target
symlink.

In `@report/src/test/java/org/hjug/refactorfirst/report/HtmlReportTest.java`:
- Around line 511-512: Update HtmlReport.printTitle to HTML-escape both project
name and project version before inserting them into the title markup. Use a
closing-title payload in the test and assert the encoded output, ensuring the
assertions reject raw HTML injection rather than merely matching unescaped
metadata.

In `@report/src/test/java/org/hjug/refactorfirst/report/ReportWriterTest.java`:
- Line 18: Create the symbolic-link probe in a unique temporary directory
instead of using the fixed “link” path, and update the helper’s cleanup to
remove the link, target, and temporary directory in a finally block; preserve
the existing success/failure result used by the symbolic-link tests.

Exercise the sanitization branch with disallowed characters.

This test configures a URL that already matches the allowlist. It passes if the sanitization at GitLogReader.java Line 118 is removed. Set the origin URL directly in Git config with a quote and an angle bracket, then assert that both characters are absent from the result.

Fix absolute Unix file:/// URI handling.

When repositoryPath is /tmp/repo, this expression searches for file:////tmp/repo/. It does not match file:///tmp/repo/src/Foo.java, so the method returns the full URI instead of src/Foo.java. The downstream SCM lookup then receives the wrong path and can produce incorrect change-proneness results on Unix.

Use Path/URI relativization, or construct the file:/// prefix without duplicating the absolute-path slash. Add a regression test for this input.

#### 6.2 Implement fix
- In `renderClassCycleVisuals()`: sanitize cycle name to identifier-safe charset `[A-Za-z0-9_]`
- Apply sanitization before all 7 downstream positions:
- JS identifier in `const <name>_dot`
- HTML `id` attributes
- JS string literals in `onclick`
- Element body text in popup buttons
- Replace `$` → `_` and strip all non-identifier characters

Generate a valid cycle identifier separate from the display label.

renderClassCycleVisuals() passes the sanitized name to generateGraphButtons(), which emits const <cycleName>_dot. The planned character filter still permits a leading digit, so 9 produces invalid JavaScript (const 9_dot). Create a non-empty identifier with a non-digit prefix, and use the HTML-escaped original name for visible text. Test empty and leading-digit names.

- Check `Files.isSymbolicLink(outputDir.toPath())` before `mkdirs()`
- Check `Files.isSymbolicLink(reportFile.toPath())` before `createNewFile()`
- Log error and return early (don't throw to avoid breaking existing callers)
- Use `Files.newBufferedWriter` with `LinkOption.NOFOLLOW_LINKS`

Resolve Maven reporting defaults before calling containReportDirectory.

When <reporting> is absent, project.getModel().getReporting() is null, so all four goals dereference it before ReportWriter.containReportDirectory runs. When outputDirectory is absent, the helper uses the literal target/site instead of Maven’s ${project.build.directory}/site. Pass the effective reporting directory at all four sites and add goal-level tests for both cases.

Path Traversal (CWE-59)

Reachability: External · Exploitability: Moderate

Reject symbolic links in every output-directory component.

Files.isSymbolicLink(reportOutputDir.toPath()) checks only the final directory entry. An intermediate symlink such as target -> /external lets mkdirs() and the report write escape the project directory. Validate each component and use descriptor-relative operations, such as SecureDirectoryStream, where supported. Add a regression test for an intermediate target symlink.

Use a unique path for the symbolic-link probe.

If the fixed link entry already exists, Files.createSymbolicLink throws FileAlreadyExistsException. The helper catches it as IOException and returns false, so all four symbolic-link tests are skipped. Create the probe in a unique temporary directory and clean up the link, target, and directory in finally.

Confirmed: HtmlReportTest.java already expects the escaped `\u003E` form (line 66-68). HtmlReportKotlinTest.java's test wasn't updated to match this same deliberate escaping change. I'll update the Kotlin test's expected string.

Good, this matches the pattern already used successfully in `HtmlReportTest.java` (`"-\\u003E"`). The fix is complete.

## Summary

The failing test `HtmlReportKotlinTest.buildClassCycleDot_kotlinSourcePaths` expected literal `->` in the generated DOT/JS output, but the PR deliberately added `toJavaScriptTemplateLiteral()` escaping of `<` and `>` to `\u003C`/`\u003E` (an XSS-hardening fix for embedding DOT content inside a JS template literal in the HTML report — part of the OpenVuln security fixes). This is confirmed by:

- `git diff origin/main..HEAD` showing the new `toJavaScriptTemplateLiteral` method that escapes `<`/`>`.
- The sibling test `HtmlReportTest.java` (`buildClassCycleDot`) already updated to expect `-\\u003E` in its assertions, i.e., the same class of test was already aligned with the new behavior.

Only `HtmlReportKotlinTest.java` was missed. I updated its expected DOT string to use `-\\u003E` instead of `->`, matching the actual (correct, security-hardened) output — consistent with the already-updated Java-source-path test.
