Lifecycle Timeline
3DescriptionCVE.org
A security flaw has been discovered in enquirer up to 2.4.1. Affected is the function Enquirer.set of the component Public Package API. The manipulation of the argument question.name results in improperly controlled modification of object prototype attributes. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report.
AnalysisAI
Prototype pollution in the enquirer npm package (versions up to 2.4.1) allows remote authenticated attackers to manipulate JavaScript Object.prototype attributes by injecting a crafted value into the question.name argument of the Enquirer.set() function. The vulnerability carries a low CVSS 4.0 score of 2.1, reflecting limited integrity-only impact scoped to the vulnerable system with no confidentiality or availability consequence. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has sufficient access (PR:L per CVSS 4.0) to supply a crafted value for the question.name argument to the Enquirer.set() function - either directly as an API consumer or indirectly through an application layer that exposes this parameter to user input. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 2.1 (Low) is consistent with the narrow blast radius: VI:L with no confidentiality or availability impact, and PR:L indicating the attacker must have some level of authenticated or authorized access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege access to an application that passes user-supplied input to enquirer's Enquirer.set() function submits a crafted question.name value such as __proto__[isAdmin]=true. The enquirer library processes this without sanitization, writing the property into Object.prototype and polluting the shared prototype chain for the entire Node.js process. … |
| Remediation | No vendor-released patched version has been identified at the time of analysis - the fix status should be monitored via the GitHub issue at https://github.com/enquirer/enquirer/issues/487 and the VulDB entry at https://vuldb.com/vuln/377113. … Detailed patch versions, workarounds, and compensating controls in full report. |
