CVE-2026-73231: Faker-Js Faker

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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 code execution. This issue is fixed in version 10.5.0.

Affected products

• Faker-Js Faker: before 10.5.0 (fixed in 10.5.0)
