CVE-2026-101900
Description
A flaw was found in Axios. This vulnerability allows an attacker to manipulate outbound network traffic by injecting arbitrary HTTP (Hypertext Transfer Protocol) headers. In environments where an attacker can exploit a separate prototype pollution flaw to modify shared object properties, the Axios fetch adapter improperly processes inherited configuration methods on request data. Consequently, an attacker can tamper with outgoing requests, potentially bypassing security controls, altering authentication tokens, or modifying backend service behavior.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
