AI Analysis
Technical Summary
Axios versions before 1.15.0 and 0.3.1 are vulnerable to a gadget-style attack chain that exploits prototype pollution in a third-party dependency. This vulnerability allows attackers to inject unsanitized header values into outbound HTTP requests made by Axios. The issue has been addressed and fixed in Axios versions 1.15.0 and 0.3.1. The CVSS 3.1 score is 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting a network attack vector with high impact but requiring high attack complexity and no privileges or user interaction.
Potential Impact
Successful exploitation can lead to injection of malicious header values in HTTP requests, potentially compromising confidentiality, integrity, and availability of affected systems. The CVSS score of 8.1 indicates a high severity impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade Axios to version 1.15.0 or later, or 0.3.1 or later, where the vulnerability is fixed. No other mitigation is indicated. Patch status is confirmed by the vendor advisory stating the issue is fixed in these versions.
