Upgrade to faker-js faker version 10.5.0 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is documented. Patch status is not explicitly stated but the fix is included in version 10.5.0.
Description
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.
