Summary

Use of a weak cryptographic algorithm in Gradle

The PGP signing plugin in Gradle before 6.0 relies on the SHA-1 algorithm, which might allow an attacker to replace an artifact with a different one that has the same SHA-1 message digest, a related issue to CVE-2005-4900.

Impact

The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES. Typical impact: compromised confidentiality or integrity of protected data.

Affected versions

org.gradle:gradle-core (< 6.0)

Security releases

org.gradle:gradle-core → 6.0 (maven)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions

  1. What is CVE-2019-16370? CVE-2019-16370 is a low-severity use of a broken or risky cryptographic algorithm vulnerability in org.gradle:gradle-core (maven), affecting versions < 6.0. It is fixed in 6.0. The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES.
  2. Which versions of org.gradle:gradle-core are affected by CVE-2019-16370? org.gradle:gradle-core (maven) versions < 6.0 is affected.
  3. Is there a fix for CVE-2019-16370? Yes. CVE-2019-16370 is fixed in 6.0. Upgrade to this version or later.
  4. Is CVE-2019-16370 exploitable, and should I be worried? Whether CVE-2019-16370 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

  5. What actually determines whether CVE-2019-16370 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
  6. How do I fix CVE-2019-16370? Upgrade org.gradle:gradle-core to 6.0 or later.
