CVE-2026-67312

axios 0.28.0 before 0.33.0 and 1.0.0 before 1.18.0 Denial of Service via formToJSON

State: Published
Severity: 6.3 Medium
Published: Aug 1, 2026

Reserved: Jul 29, 2026

Description

axios versions from 0.28.0 before 0.33.0 and from 1.0.0 before 1.18.0 contain uncontrolled recursion in formDataToJSON (exposed as axios.formToJSON() and used internally when serializing FormData with Content-Type: application/json). When an application passes attacker-controlled FormData field names, a field name with thousands of nested bracket-delimited segments causes unbounded recursion in buildPath(), exhausting the JavaScript call stack (RangeError: Maximum call stack size exceeded) and causing denial of service for that request, or process termination in applications without appropriate error handling.
