Vulnerability Data

Faker generates massive amounts of fake data in the browser and Node.js. Prior to 10.5.0, the faker.helpers.fake method in src/modules/helpers/eval.ts allows attacker-controlled fake templates to access the Function constructor through fakeEval.resolveProperty when a function returns another function, enabling arbitrary JavaScript…

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect eval injection vulnerabilities before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules against dynamic code execution of untrusted input.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

A.8.28 Secure coding partial match
prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

A.8.31 Separation of development, test and production environments none match
none

Separation of environments limits the blast radius if eval injection occurs in non-production.
