CVE-2024-21529: Prototype Pollution in dset
The dset package versions before 3.1.4 are vulnerable to prototype pollution due to improper sanitization of user input in the dset function. This vulnerability allows attackers to inject malicious properties via the __proto__ object property, which can affect all objects in the program recursively. The vulnerability has a high severity with a CVSS score of 8.8.
AI Analysis
Technical Summary
CVE-2024-21529 describes a prototype pollution vulnerability in the dset package prior to version 3.1.4. The issue arises because the dset function does not properly sanitize user input, allowing an attacker to manipulate the built-in Object prototype via the __proto__ property. This recursive assignment can lead to widespread modification of objects within the application environment, potentially causing unexpected behavior or security issues. The vulnerability is remotely exploitable without authentication and requires no user interaction.
Potential Impact
Successful exploitation of this vulnerability can lead to modification of the global Object prototype, which may cause denial of service, data corruption, or other unpredictable behavior in applications using the affected dset versions. The CVSS score of 8.8 indicates a high impact, with high exploitability and no required privileges or user interaction.
Mitigation Recommendations
No official patch or remediation level is currently confirmed. Versions prior to 3.1.4 are vulnerable, so upgrading to version 3.1.4 or later (once confirmed) is recommended. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
