AI Analysis
Technical Summary
This vulnerability affects the enquirer package up to versions 2.4.0 and 2.4.1. The issue lies in the Enquirer.set function of the Public Package API, where manipulation of the question.name argument allows improper modification of object prototype attributes. This can lead to prototype pollution, which may affect application behavior or security. The vulnerability can be triggered remotely, requires low privileges, and no user interaction is needed. The CVSS 4.0 base score is 5.3, indicating medium severity. No official fix or patch has been documented in the provided data.
Potential Impact
The vulnerability allows an attacker with low privileges to remotely manipulate object prototype attributes via the question.name parameter in the Enquirer.set function. This can lead to prototype pollution, potentially causing unexpected behavior or security issues in applications using the affected versions of enquirer. There is a public exploit available, increasing the risk of exploitation. However, no direct impact such as code execution or data disclosure is explicitly stated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch has been documented, users should monitor the enquirer project for updates. Until a patch is available, avoid using affected versions 2.4.0 and 2.4.1 if possible, or apply any recommended workarounds from the vendor.
