CVE-2026-67317 (GCVE-0-2026-67317)

Vulnerability from cvelistv5 – Published: 2026-08-01 12:22 – Updated: 2026-08-03 18:25

Title

axios 1.7.0 before 1.18.0 maxBodyLength Bypass via ReadableStream

Summary

axios versions 1.7.0 before 1.18.0 fail to enforce maxBodyLength for WHATWG ReadableStream request bodies in the fetch adapter when Content-Length cannot be determined. Attackers can supply unknown-length stream data to bypass upload size limits and cause uncontrolled network egress or resource exhaustion.

Severity

6.3 (Medium)
