You are auditing a third-party vendor's CI/CD pipeline integration. You notice they pull dependencies from public mirrors without pinning them to specific hashes. What is the primary security risk here?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Version hijacking due to lack of immutability.
Without hash pinning (e.g., package-lock.json or yarn.lock), an attacker can perform a 'version hijacking' attack by uploading a malicious version with the same semver string.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Incompatible library versions.
Why it's wrong here
Incompatibility is an operational issue, not a supply chain security risk.
- ✗
Excessive bandwidth usage.
Why it's wrong here
Bandwidth is irrelevant to the security of the supply chain.
- ✓
Version hijacking due to lack of immutability.
Why this is correct
Lockfiles ensure that the exact byte-for-byte code is used in every build.
- ✗
Failure to meet license requirements.
Why it's wrong here
Licensing is a legal concern, not a code integrity risk.
