CVE-2026-73231
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk5th percentile - higher than 5% of all known CVEs
Summary
Faker, a tool that generates massive amounts of fake data in the browser and Node.js, prior to version 10.5.0 has a vulnerability in the faker.helpers.fake method that allows attacker-controlled fake templates to access the Function constructor through fakeEval.resolveProperty when a function returns another function, enabling arbitrary JavaScript code execution.
Risk Assessment
An attacker can exploit this vulnerability to execute arbitrary JavaScript code in the context of the application using Faker, potentially leading to application compromise or data theft.
Recommendation
Update Faker to version 10.5.0 or later, which fixes this vulnerability. Additionally, do not use untrusted templates.
Original NVD description (English source)
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.
