Fix hard-coded secrets in Java and Spring Boot
==============================================

Bind the key from the Spring Environment with @ConfigurationProperties and
check it in the record's constructor, so a missing or blank value stops the
app at startup. Supply it as FORECAST_APIKEY or a mounted secret from your
secret store, never in a committed application*.properties file, and send it
in the Authorization header, not the URL.

What is in this archive
-----------------------
hardcoded-secrets/java-spring/   the project: three implementations of the same code and one test suite
  src/main/java/com/example/forecast/impl/VulnerableForecast.java   (vulnerable)
  src/main/java/com/example/forecast/impl/FixedForecast.java   (fixed)
  src/main/java/com/example/forecast/impl/WrongForecast.java   (a plausible fix that still fails)
run-all.mjs   runs the tests in all three modes and checks the results (Node.js only)
LICENSE-CODE.txt

Run it
------
  Tested with OpenJDK 21.0.12.1 (Homebrew), Maven 3.9.16. run-all.mjs needs
  Node.js 22 or later. Supported versions:
  https://softwaresecurity.com/fix/versions/

  From the hardcoded-secrets/java-spring folder, install the dependencies once
  (this needs network access):

    mvn -B -q test

  Then run the tests. IMPL chooses the implementation the tests load:

    # every test passes
    IMPL=fixed mvn -B -o -q test
    # an exploit test fails
    IMPL=vulnerable mvn -B -o -q test
    # a test fails
    IMPL=wrong mvn -B -o -q test

  The JUnit report is written to target/surefire-reports/TEST-*.xml. To run all
  three modes and check the results in one step, run the harness from this top
  folder (it needs only Node.js; --install runs the install step first):

    node run-all.mjs --install hardcoded-secrets/java-spring
    node run-all.mjs hardcoded-secrets/java-spring

Verified

  11 October 2026 on macOS 27.0 (Darwin 27.0.0, arm64), with java OpenJDK
  21.0.12.1 (Homebrew), maven 3.9.16, springBoot 4.1.1, springFramework 7.0.9,
  tomcat 11.0.26, jackson 3.1.7, junitJupiter 6.0.3. Versions and results hold
  for that date: run the tests with your own versions before relying on the fix.
