Allocation of Resources Without Limits or Throttling in axios - CVE-2026-42034

Vulnerability identifier: #VU127602

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-42034

CWE-ID: CWE-770

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the HTTP adapter native http/https transport path when sending streamed request bodies with maxRedirects set to 0. A remote attacker can send an oversized streamed upload to cause a denial of service.

The issue affects only stream request bodies; buffered request bodies and requests using default or nonzero redirect handling follow different enforcement paths.
